1. Program to find the simple interest
#include <stdio.h>
int main () {
int p , t , r , si ;
printf ("Enter the principle: " );
scanf ("%d" , & p );
printf ("Enter the time: " );
scanf ("%d" , & t );
printf ("Enter the rate: " );
scanf ("%d" , & r );
si = (p * t * r ) / 100 ;
printf ("Simple Interest is %d" , si );
return 0 ;
}
> Enter the principle: 2000
> Enter the time: 2
> Enter the rate: 10
> Simple Interest is (ans)
2. Simple program that uses switch statement
#include <stdio.h>
int main () {
int choice , a , b ;
printf ("Enter 1 for addition!\n" );
printf ("Enter 0 to exit!\n" );
scanf ("%d" , & choice );
switch (choice ) {
case 1 :
printf ("Enter any two number: " );
scanf ("%d %d" , & a , & b );
printf ("The sum is %d" , a + b );
break ;
case 2 :
return 0 ;
default :
break ;
}
}
> Enter 1 for addition
> Enter 0 to exit
> 1
> Enter any two number: 2 10
> The sum is 12
3. Program that prints the multiplication table of any number
#include <stdio.h>
int main () {
int num ;
printf ("Enter any number: " );
scanf ("%d" , & num );
for (int i = 1 ; i <= 10 ; i ++ ) {
printf ("%d x %d = %d\n" , num , i , num * i );
}
return 0 ;
}
> Enter any number: 3
> 3 x 1 = 3
> 3 x 2 = 6
> 3 x 3 = 9
> 3 x 4 = 12
> 3 x 5 = 15
> 3 x 6 = 18
> 3 x 7 = 21
> 3 x 8 = 24
> 3 x 9 = 27
> 3 x 10 = 30
