Flowchart of if else statement  

In the last program the test expression is number%2==0, if it is evaluated to true then the body of if i.e. Number is even will be processed otherwise it prints Number is odd.

Flowchart of if statement:

In case if statement, the condition will be evaluated, if it is true it executes the statement/s. Whether the condition is true or false the statement/s written after the if statement will be always executed.

Example: To check the number is zero.

#include

main()

{ 

int num; 

printf("\nEnter a number to check "); 

scanf("%d",&num); 

if(num<0 nbsp="" stdio.h="">

 printf("\nNumber=%d",num); 

printf("\nThe if statement in C programming is easy."); 

}
