Question

The function ??????????(??, ??) for two positive integers 1 ? ??, and 1 ? ??, is defined as the following: ??????????(??, 1) = ??; ??????????(??, ??) = ?? + ??????????(??, ?? ? 1)
Write a recursive version of ??????????() in C or C++ and then use this program to develop a MIPS program that gets an input of two integers 0 < ?? ? 255, and 0 < ?? ? 255, and returns the result of ??????????(??, ??) in $v1.

Explanation / Answer

#====================================================================================

The C program is :

#include <stdio.h>

int rmult(int a, int b)
{
    if(b==1)
    {
        return(a);
    }
    else
    {
        return(a+rmult(a,b-1));
    }
}
int main(void) {
int a,b,v1;
scanf("%d",&a);
scanf("%d",&b);
v1=rmult(a,b);
return 0;
}
