函数strtok和strchr的使用

#include <string.h>#include <stdio.h>int main(void) {char input[16] = "abc,d";char *p;p = strtok(input, ",");if (p)printf("%s\n", p);p = strtok(NULL, ",");if (p)printf("%s\n", p);return 0;}

#include<string.h>#include<stdio.h>int main() {char string[17];char *ptr, c = 'r';strcpy(string, "This is a string");ptr = strchr(string, c);if (ptr) {printf("The charactor %c is at position:%d\n", c, ptr - string);} elseprintf("The charactor was not found");return 0;}
