Try this:
main.c:
-------
1 #include <stdio.h>
2 #include <stdlib.h>
3
4 int main( int argc, char * argv[] )
5 {
6
7 char * stringVar = argv[1];
8 printf( "stringVar = %s\n", stringVar );
9 int numberVar = atoi( stringVar );
10 printf( "numberVar = %d\n", numberVar );
11
12
13 return 0;
14 }
> gcc -g -Wall -o args main.c
> ./args 10
stringVar = 10
numberVar = 10
