Im doing a code "test" from the c++ book I am currently reading, the objective is to ask for input using a function and output data using a function, while keeping the data in main.
I finished it and it works, but I want to make the program not accept char's as input but accept int's, as a form of personal enrichment. :)
#include <iostream>
void info(int& x, char name [])
{
std::cout<<"Enter a number, 0 to end: ";
std::cin>>x;
if((x >= 'a' && x <= 'z') || (x >= 'A' && x <= 'Z'))
{
std::cout<<"\nPlease don't enter a letter\n";
std::cout<<"I will convert it for you anyway: ";
x = (static_cast<int>(x));
std::cout<<x;
}
if(x != 0)
{
std::cout<<"\nEnter a name, less than 15 characters: ";
std::cin>>name;
}
}
void output_data(const int x, const char name[])
{
std::cout<<"\nThe name was: "<<name;
std::cout<<"\nThe number was: "<<x<<"\n\n";
}
int main()
{
int x(0);
char name[15];
for(;;)
{
info(x, name);
if(!x)
break;
output_data(x, name);
}
return 0;
}The problem is in the function named info, lines 8-13.
I want it to accept int's but not chars, i've tried a do-while loop but I cant find a way for the program to distinguish between a char and its ANSI representation. I hope its not an easy trick, I might have forgotten, I dont feel very good at the moment.
