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”); for(counter=0;counter<argc;counter++) { puts(argv[counter]); } return(0); } |
How to run:
- Name of program is supposed to be file.C
- Make its executable by compiling it.
- Go to Dos Shell from file menu.
- You need to type :file this is command line
The output of the program would be :
