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:
