C Question
Can we use integer pointer in command line arguments
main(int argc,char *argv[])
{
......;
......;
}
Here argc is an interger variable and indicates the number of parameters passed.
argv is an array of pointers to characters
My doubt is I seen an program using
main(int argc, int*argv[])
{
......;
......;
}
is it valid can we use argv as an array of pointers to integers?

#include <stdio.h>
int main(int argc, int*argv[])
{
int a=3;
int b=4;
printf("\n%s", (char*)argv[1]);
return 0;
}
Command Line arguments : abcd
Output : abcd
I have compiled the code above and worked perfectly. It seems that int* argv[] is permitted. I think this is compiler specific some will allow it and other will not. You have to provide appropriate casting for the argument passed.
