i have writen a program that asks the user to input letters and it will change it to upper case. i have done this by using the common way of "toupper". i then got told that i cant have any letter manipulation or string commands to do this. can anyone help as to do this?
here is the code i had before...
Code:#include <iostream>
#include <iomanip>
#include <ctype.h>
using namespace std;
int main()
{
char input[25];
int i = 0;
cout <<"Please enter a word of mixed letters eg - MiXeD LeTtErS";
cin >> input;
for(;;)
{
if (input[i] == '\0') break;
else
{
input[i] = toupper(input[i]);
}
i++;
}
cout <<input;
system("pause");
}
