NOTE: All Codes are written and tested in DEV C++

Basic Requirement to learn this code:

Example:1:

case 1: int a,b,sum;
printf("\nenter two no. to add:");
scanf("%d%d",&a,&b);
sum=a+b;
printf("sum=%d",sum);
break;
case 2: int i,n;
printf("\nenter a number upto which u want to print the numbers from one");
scanf("%d",&n);
for(i=1;i<=n;i++)
printf("\n%3d",i);
