Below is an example of a C program that finds the largest among five numbers. The program compares each number with the current maximum and updates the maximum whenever a larger number is encountered. Method 1 : #include<stdio.h>#include<conio.h>main(){int a,b,c,d,e;printf(“Enter First the Number : “);scanf(“%d”,&a);printf(“Enter Second the Number : “);scanf(“%d”,&b);printf(“Enter Third the Number : “);scanf(“%d”,&c);printf(“Enter Foruth the Number : “);scanf(“%d”,&d);printf(“Enter Fifth the Number : “);scanf(“%d”,&e);if((a>b)&&(a>c)&&(a>d)&&(a>e)){printf(“%d is the Biggest Number.”,a);}else if((b>a)&&(b>c)&&(b>d)&&(b>e)){printf(“%d is the Biggest Number.”,b);}else if((c>a)&&(c>b)&&(c>d)&&(c>e)){printf(“%d is the Biggest Number.”,c);}else if((d>a)&&(d>b)&&(d>c)&&(d>e)){printf(“%d is the Biggest Number.”,d);}else{printf(“%d is the Biggest Number.”,e);}} Output : Method 2 : #include<stdio.h>#include<conio.h>main(){int a,b,c,d,e,max;printf(“Enter First the Number : “);scanf(“%d”,&a);printf(“Enter Second the Number : “);scanf(“%d”,&b);printf(“Enter Third the Number : “);scanf(“%d”,&c);printf(“Enter Fourth the Number : “);scanf(“%d”,&d);printf(“Enter Fifth the Number : “);scanf(“%d”,&e);if(a>b)max=a;elsemax=b;if(c>max)max=c;if(d>max)max=d;if(e>max)max=e;printf(“Biggest Number is : %d”,max);} Output :
