multiplication of two variable

 #include<stdio.h>  

int main()        

{

    int a;      

    int b;

    printf("enter the first number a\n");

    scanf("%d", &a);

    printf("enter the second number b\n");

    scanf("%d", &b);

    printf("the answer is %d\n", a*b);    

    return 0;

}

// project:_4 (multiplication)

// yearly sip calculator based on simple intrest

// enter sip capital amount

// enter the number of years

// your captital will be

// enter the rate of intrest

// your return will be & retuen % will be

#include <stdio.h>

int main ()

{

    int c,t,r;

    printf ("enter SIP capital amount: ");

    scanf ("%d", &c);

    printf ("enter the number of years: ");

    scanf ("%d", &t);

    printf ("enter the rate of intrest: ");

    scanf ("%d", &r);

    printf ("your return amount will be: %d\n",((c*t*12*r)/100));

    printf ("your final value will be: %d",((c*t*12)+(c*t*12*r)/100));

    return 0;

}

output:_

enter SIP capital amount: 1000 enter the number of years: 1 enter the rate of intrest: 10 your return amount will be: 1200 your final value will be: 13200
