C program to find the greatest number among four numbers | My CS Tutorial

In this tutorial we will learn how write a C program that find the greatest number among four numbers.
We will write a C program that find the biggest number among four numbers.

Solution:

• In this program we will use two header files.
• In this program we will use four variables a,b, c and d.
• We declared these four variables a,b,c and d in int data type.
• Then we will enter the value of a,b,c and d.
• We will use if else statement with some conditions which is (a>b),(a>c) and (b>c) and more.
• And after it we will print the statement or body.

• When we use these statement the condition execute own statement.
• When the if condition is false it execute else statement.

C program code


#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,c,d;
clrscr();

printf("\n Enter the value of a=");
scanf("%d",&a);

printf("\n Enter the value of b=");
scanf("%d",&b);

printf("\n Enter the value of c=");
scanf("%d",&c);

printf("\n Enter the value of d=");
scanf("%d",&d);

if(a>b)
{
if(a>c)
{
if(a>d)
printf(" a is greatest");
else
printf(" d is greatest");
}
}
else
if(b>a)
{
if(b>c)
{
if(b>d)
printf(" b is greatest");
else
printf(" d is greatest");
}
}
else
if(c>a)
{
if(c>b)
{
if(c>d)
printf(" c is greatest");
else
printf(" d is greatest");
}
}
getch();
}



Output 1:

Output 2:

we will find the greatest number among four numbers so we take four variables a,b,c and d and use the if else statement.
We use some conditions to find the greatest number.

  When we use if or else statement inside a if statement or else statement this is called nesting of if else statement.
