HI. my coding not display an output as i want. my question project ask me to make menu interface application which is we can choose any number on menu. but my coding continued to calculate until end which is wrong. its will calculate when i choice the menu 3-5. anyone can fix this?

#include<iostream>
#include<string>

float TPGP (float);
int TPC (int);
float PCGPA (float, int);

int main()
{
string name, matric, coursecode;
char another;
float sum1, sum3, Ppoint, Cpoint, a, c;
int *pointer1, *pointer2, sum2, sum4, i, j, b, d;

You already have thread http://www.cplusplus.com/forum/general/244902/
on this homework. You could have continued there.

Please, use code tags <> when posting code. See http://www.cplusplus.com/articles/jEywvCM9/

question project ask me to make menu interface application which is we can choose any number on menu.

I see no attempt to do anything like that in your code.
