Command Line Arguments in C


Command Line Arguments in C

It is possible to values at command prompt using command line arguments in C. We need to specify the name of program followed by values we want to pass as arguments .

To implement command line arguments main() must have two parameters as: main ( int argc, char *argv[] )

  • argc specifies the number of arguments passed at command line.
  • *argv[] specifies the values passed as arguments at command line.
Program for command line arguments.
#include <stdio.h>
int main ( int argc, char *argv[] )
int counter;
printf(“Command line arguments”);
