C Decision Making

C supports the following two types of decision making statements:

You can further divide both the above statements into the following parts:

C Decision Making Statements Example

Here is an example demonstrates how to use decision making statements in C programming to control the program.

/* C Decision Making Example */

#include<stdio.h>
#include<conio.h>
void main()
{
   int num;
   clrscr();
   printf("Enter a number: ");
   scanf("%d", &num);
   if(num>10)
   {
      printf("The number is greater than 10.");
   }
   else
   {
      printf("The number is less than 10.");
   }
   getch();
}

Here are the two sample runs of the above C decision making program:

Let's take another program on decision making or selection statements in C.

/* C Decision Making Program */

#include<stdio.h>
#include<conio.h>
void main()
{
   int num;
   clrscr();
   printf("Enter 10.");
   scanf("%d", &num);
   if(num == 10)
      printf("Well Done!");
   else
      printf("Oops!");
   getch();
}

Here are the two sample runs of the above selection statements program in C.

Here is another example also demonstrates decision making statement in C

/* C Decision Making */

#include<stdio.h>
#include<conio.h>
void main()
{
   int mark;
   clrscr();
   printf("Enter marks obtained: ");
   scanf("%d", &mark);
   if(mark>80)
      printf("You are passed!");
   else
      printf("You are failed!");
   getch();
}

Here are the two sample runs of the above C decision making program:
