Command Prompt input

[Firecore]

How do u get input from the command prompt as a program argument? like there is the javac program that accepts arguments to work.

I believe you use

int main(int argc, char *argv[])

The command line arguments are stored in argv. So if you typed:

myProg.exe My name is Ganon.

then argv[1] contains "My\0", argv[2] contains "name\0", and so on.

argc is the number of arguments passed; in the previous example, argc holds 4.

myProg.exe My name is Ganon.

then argv[1] contains "My\0", argv[2] contains "name\0", and so on.

argc is the number of arguments passed; in the previous example, argc holds 4.

Remember that argv[0] contains the program name "myProg.exe" so in your example argc actual holds 5.

Compile and run this, put something(anything) on the command line

#include <stdlib.h>
#include <stdio.h>
 
 
int main(int argc, char **argv)
{
    int ix;
 
    for(ix=0; ix<argc; ix++)
    {
        printf("%3d: %s\n", ix, argv[ix]);
    }
 
    return 0;
}
