Control statements in c

control statements in c

Control statements in C are used to control the flow of execution of a program. There are three types of control statements in C:

1.Conditional Statements:

Conditional statements allow us to execute different blocks of code depending on whether a condition is true or false. The two types of conditional statements in C are:

if statement: It executes a block of code only if a condition is true.

switch statement: It allows us to test a variable against a series of values and execute a block of code based on the matching value.

2.Looping Statements:

Looping statements allow us to execute a block of code repeatedly as long as a certain condition is true. The three types of looping statements in C are:

for loop: It is used to execute a block of code for a specified number of times.

while loop: It is used to execute a block of code as long as a condition is true.

do-while loop: It is similar to the while loop, but the block of code is executed at least once before the condition is checked.

3.Jump Statements:

Jump statements allow us to transfer control to another part of the program. The three types of jump statements in C are:

break statement: It is used to terminate a loop or a switch statement.

continue statement: It is used to skip the current iteration of a loop and move to the next iteration.

goto statement: It is used to transfer control to a labeled statement within the same function.

These control statements provide us with the ability to create complex programs with varying behaviors based on different conditions.

decision making statements in c

In C, decision-making statements are used to control the flow of execution of a program based on certain conditions. The three primary decision-making statements in C are:

1.if statement:

The if statement is used to execute a block of code if a particular condition is true. If the condition is false, then the code inside the if statement is not executed. The syntax of the if statement is as follows:

if (condition)
{
   // code to be executed if condition is true
}

2.if-else statement:

The if-else statement is used to execute a block of code if a particular condition is true and another block of code if the condition is false. The syntax of the if-else statement is as follows:

code:,

if (condition)
{
   // code to be executed if condition is true
}
else
{
   // code to be executed if condition is false
}

3.switch statement:

The switch statement is used to select one of several blocks of code to execute based on the value of a variable or expression. The syntax of the switch statement is as follows:

switch (expression)
{
   case constant1:
      // code to be executed if expression is equal to constant1
      break;
   case constant2:
      // code to be executed if expression is equal to constant2
      break;
   ...
   default:
      // code to be executed if expression doesn't match any of the constants
}

These decision-making statements are essential in C programming, as they allow developers to create flexible and dynamic programs that can respond to changing conditions during runtime.

looping statements in c

In C, looping statements are used to execute a block of code repeatedly until a particular condition is met. The three primary looping statements in C are:

1.while loop:

The while loop is used to repeatedly execute a block of code as long as a particular condition is true. The syntax of the while loop is as follows:

while (condition)
{
   // code to be executed repeatedly as long as condition is true
}

2.for loop:

The for loop is used to repeatedly execute a block of code a specific number of times. The syntax of the for loop is as follows:

for (initialization; condition; increment/decrement)
{
   // code to be executed repeatedly until condition is false
}

3.do-while loop:

The do-while loop is used to repeatedly execute a block of code at least once and then continue executing the block as long as a particular condition is true. The syntax of the do-while loop is as follows:

do
{
   // code to be executed at least once
}
while (condition);

These looping statements are essential in C programming, as they allow developers to automate repetitive tasks and create efficient, scalable programs. By using looping statements in conjunction with decision-making statements, developers can create complex algorithms and logic flows that can handle a wide variety of use cases.

jumping statements in c

In C, jumping statements are used to transfer control of a program to a different section of code within the same function or to a different function altogether. The three primary jumping statements in C are:

1.break statement:

The break statement is used to exit from a loop prematurely. When executed inside a loop, the break statement immediately terminates the loop and transfers control to the statement following the loop. The syntax of the break statement is as follows:

while (condition)
{
   // code to be executed repeatedly as long as condition is true
   if (some_condition)
   {
      break; // exit loop prematurely
   }
}

2.continue statement:

The continue statement is used to skip the current iteration of a loop and continue with the next iteration. When executed inside a loop, the continue statement immediately transfers control to the next iteration of the loop. The syntax of the continue statement is as follows:

for (int i = 0; i < 10; i++)
{
   if (i == 5)
   {
      continue; // skip iteration when i = 5
   }
   // code to be executed for all other values of i
}

3.return statement:

The return statement is used to exit a function prematurely and return a value to the calling function. When executed inside a function, the return statement immediately transfers control back to the calling function and returns a value, if specified. The syntax of the return statement is as follows:

int myFunction(int x)
{
   if (x < 0)
   {
      return -1; // exit function prematurely and return -1
   }
   // code to be executed for all other values of x
   return x; // return x to calling function
}

These jumping statements are essential in C programming, as they allow developers to create more efficient and flexible programs by controlling the flow of execution and handling errors or exceptions gracefully.

point to glance for control statements in c

In C, control statements are used to control the flow of execution of a program based on certain conditions. The primary control statements in C include:

Decision-making statements:

Decision-making statements allow developers to execute a block of code based on whether a particular condition is true or false. The three primary decision-making statements in C are if, if-else, and switch.

Looping statements:

Looping statements allow developers to execute a block of code repeatedly until a particular condition is met. The three primary looping statements in C are while, for, and do-while.

Jumping statements:

Jumping statements allow developers to transfer control of a program to a different section of code within the same function or to a different function altogether. The three primary jumping statements in C are break, continue, and return.

By using these control statements effectively, developers can create efficient, flexible, and robust programs that can handle a wide variety of use cases. It is essential to understand the syntax and proper usage of these control statements to write high-quality code in C. It is also important to note that improper use of control statements can lead to hard-to-find bugs and other issues in your code, so it is crucial to use them carefully and deliberately.
