How can I get arguments from standard input in C? [duplicate]

Question

I have a string that I want to execute in C file and I'd like to get the string from standard input.

echo "Here is some random text.\n" | ./main.c

Answer 1

Read from stdin like any other FILE stream.

#include<stdio.h>

int main()
{
    char line[BUFSIZ];
    fgets(line, sizeof(line), stdin);
    printf("stdin: %s", line);
}
