Translate the following C/C++ code into MIPS Assembly Code:
void chico(int *X, int Y, int Z)
{
*X = Y/4 - Z*10 + *X*8;
}
int main()
{
int J, K, L, M;
cin >> J, K, L;
chico ( &J, K, L);
M = J - (K + L);
cout << M;
return 0;
}
Solution
Program:
#include
using namespace std;
void chico(int *X, int Y, int Z)
{
*X = Y/4 - Z*10 + *X*8;
}
int main()
{
int J, K, L, M;
cin >> J,K,L;
chico ( &J, K, L);
M = J - (K + L);
cout<<\"value\"<< M;
return 0;
}
The above code returns the following Mips code :
