String functions help

I keep getting this error when I am compiling my program. I am trying to read in this array and then convert all the characters to upper-case, but it is ging me this:

Code:

error C2664: 'toupper' : cannot convert parameter 1 from 'char [30]' to 'int'
        This conversion requires a reinterpret_cast, a C-style cast or function-style cast
Error executing cl.exe.

Code:

#include <iostream.h>
#include <fstream.h>
#include <iomanip.h>
#include <ctype.h>
#include <stdlib.h>
#include <string.h>

//Global variables
ifstream infile;
ofstream outfile;

typedef char str[30];

//function prototypes
void tocaps(str []);

int main()
{

int n[30],m[30];
str name[30];


	infile.open("in599A.dat");
	while(!infile.eof())
	{
		for(int i=0;i<23;i++)
		{
		infile >> n[i];
		infile >> m[i];
		infile.getline(name[i],30);
		cout << n[i] << endl << m[i] << endl
		<< name[i] << endl;
		}
		
		//change to caps
		tocaps(name);
		//take off the last characters of middle name
		//compare to second file
		//add dashes to social security number and add dashes to phone number

		//sort 
		//binary search

	}
	
	return 0;
}

void tocaps(str name[])
{
	for(int i=0;i<23;i++)
		{
			name[i]=toupper(name[i]);
		}
		for(i=0;i<23;i++)
		cout << name[i] << endl;
}

toupper() works on single characters, not entire strings. You'd need a nested loop.

Code:

typedef char str[30];
...
str name[30];

See the issue now?

Quzah.

cool, thank you. I had a different example in my notes.
