Y/N question to trigger function.

[Markus3400]

I have this weird problem. It should be very simple.
Let the user choose to save the n (number of rows and columns in a nxn matrix) and save the matrix A(nxn)

if the user press y, the void function SaveFileA will commence, and if other then y is pressed, it will not. But as of now, it just gives me the "You choose not to save"

Where's the faulty programming?
This is part of a bigger program with other features, so i've only copy pasted the part that is malfunctioning.

#include <iostream.h>
#include <math.h>
#include <time.h>
#include <iomanip.h>
#include <stdlib.h>
#include <stdio.h>
#include <fstream.h>

#define nMax 8


void SaveFileA(double A[nMax][nMax], int &n);

main()
{
	double A[nMax][nMax], An[nMax][nMax], lamn[nMax], S[nMax][nMax], XN[nMax][nMax];
	int Valg1234,a,b,c,d,i,j,n,ValgTastA48,
	char SaveA;
	ofstream UdfilA;
        cout<<"\nDo you wish to save n and A(nxn)? press y/n  ";
			cin>>SaveA;
			if(SaveA=='y')
			{
				SaveFileA(A,n);
			}
			else
			{
			cout<<"You choose not to save\n";
			}
}
void SaveFileA(double A[nMax][nMax], int &n)  //void function save to AMat.txt
{
		int i, j;
		cout<<"You choose to save A";
		ofstream UdFil;
		UdFil.open("AMat.txt");
		UdFil<<n<<"\n";
		for (i=0; i<n; i=i+1)
			{
				for (j=0; j<n; j=j+1)
				{
					UdFil<<A[i][j];
				}
			cout<<"\n";
			}
		UdFil.close();
}

It seems you have a very old non standard compiler. It shouldn't compile.

On line 18: at the end of the line there's a , where a ; is supposed to be. Does the compiler treat SaveA as an int? Then it would of course not contain 'y'

Try:

if('y' == SaveA || 'Y' == SaveA)

ooh embarrassing! :D
it was the , instead of the ;
it did compile tho. wierd. must have been because of the char saveA; underneath

thanks a lot, it works now :D
