argc, argvは定型として覚える。 #include <stdio.h> int main(int argc, char *argv[]){ int count = 0; while(count < argc){ printf("%d = %s\n", count++, argv[count]); } return 0; } C言語の目次</stdio.h>

仮引数は関数で受け取る時の変数。実引数は関数に渡す時の値 #include <stdio.h> void myfunc(char str[], int num); int main(void){ myfunc("Hoge is Hoge!!", 100); return 0; } void myfunc(char str[], int num){ printf("%s -- %d", str, num); } C言語の目次</stdio.h>
