练习7-10 查找指定字符

#include<stdio.h>

int main(void)
{
    int i;
    char str[80];
    char ch, temp;

    ch = getchar();        //需要查找的字符
    temp = getchar();    //第一行回车

    i = 0;
    while ((str[i] = getchar()) != '\n')
    {
        i++;
    }
    str[i] = '\0';

    int index = -1;
    for (i = 0; str[i] != '\0'; i++)
    {
        if (str[i] == ch)
        {
            index = i;
        }
    }

    if (index == -1)
    {
        printf("Not Found\n");
    }
    else
    {
        printf("index = %d\n", index);
    }

    return 0;
}
