Argc Vs Argv

You will see argc and argv in

int main(int argc, char *argv[]) {
 //...
}

• argc: argument count
• argv argument array

For example, if we're calling

./main first second third

In this case, argc is 4.

argv is an array with ["./main", "first", "second", "third"]

#include <stdio.h>
#include <stdlib.h>

char* parseArgv(int argc, char* argv[]);

int main(int argc, char* argv[]) {
    printf("argc %d \n", argc);
    printf("argv %s \n", parseArgv(argc, argv));
}


char* parseArgv(int argc, char* argv[]) {
    char* result = (char*) malloc(100 * sizeof(char));

    int pointer = 0;
    for (int i = 0; i < argc; i++) {
        for (int j = 0; argv[i][j] != '\0'; j++) {
            result[pointer++] = argv[i][j];
        }

        result[pointer++] = ' ';
    }

    result[pointer] = '\0';

    return result;
}
