I want to convert two C++ programs into MIPS assembly. Both programs compute if a given integer is prime or not. They both contain the same main() pretty much, but one uses an iterative function while one uses a recursive function. I am not too good with MIPS so I wanted to know if anyone here could offer any help.

I want to use the MIPS command "syscall" for the C++ "cout" and "cin" statements. I also want to use the "rem" MIPS instruction for the C++ mod operation.

I will paste the two C++ programs below:

Iterative:

```
#include <iostream>
using namespace std;
bool isPrime(int n);
int main()
{
int n;
cout << "Please enter a positive integer to be tested: ";
cin >> n;
cout << "\nYou entered n = " << n << endl;
if ( isPrime(n) )
cout << "\nIterative isPrime retuned TRUE\n\n";
else
cout << "\nIterative isPrime retuned FALSE\n\n";
return ( EXIT_SUCCESS );
}
// Iterative Primality Tester Algorithm
// Input: Positive integer n >=2
// Output: true if n is prime
// false if n is composite
bool isPrime(int n)
{
int i;
if ( n < 2 )
{
cout << "The number entered is less than 2!\n";
exit(EXIT_FAILURE);
}
for (i = 2; i < n; i++)
if ( ( n % i ) == 0 ) return false;
return true;
}
```

And the recursive program:

```
#include <iostream>
using namespace std;
bool isPrime(int n);
bool searchFactor(int range, int n);
int main()
{
int n;
cout << "Please enter a positive integer to be tested: ";
cin >> n;
cout << "\nYou entered n = " << n << endl;
if ( isPrime(n) )
cout << "\nRecursive isPrime retuned TRUE\n\n";
else
cout << "\nRecursive isPrime retuned FALSE\n\n";
return ( EXIT_SUCCESS );
}
// Recursive Primality Tester Algorithm
// Input: Positive integer n >=2
// Output: true if n is prime
// false if n is composite
bool isPrime(int n)
{
int i;
if ( n < 2 )
{
cout << "The number entered is less than 2!\n";
exit(EXIT_FAILURE);
}
return !searchFactor(2, n);;
}
// Recursive search for factors
// Input: Positive integer n >=2
// Positive integer range
// Output: true if exists an integer in [range, n-1] that is a factor of n (i.e., n is not prime)
// false if there is no such integer
bool searchFactor(int range, int n)
{
if ( range >= n ) return false;
if ( ( n % range ) == 0 ) return true;
else return searchFactor(range+1, n);
}
```

I appreciate it guys! :)
