c++ - 字符串 : Finding if the first word is repeated using strcmp

Question

我有一个作业，我必须输入要比较的名称数量。然后我要看看我打印的名字中是否重复了打印的名字。例如，如果我输入 5 Reagan, Bush, Reagan, Bush, Clinton，它会打印出“The first name was repeated”，但如果我输入 Davis 代表里根中的任何一个，它会说不。我尝试了一个 for 循环和 if 语句，但我似乎无法找到正确的输出。我正在使用 Dev C++，这是我目前所拥有的。

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main () {
    char curname[30], firstname[30];
    int num, i, freq = 1;


    printf("How many names do you want to enter?\n");
    scanf("%d", &num);
    printf("What is the first name?");
    scanf("%s", firstname); 
    printf("Enter each of their names.\n");
    for (i=0; i<num; i++) {

        scanf("%s", curname);

        if (i==0) {
          strcmp(curname, firstname) != 0;
          printf("The first name in the list was repeated.\n"); 
        }
        else if (strcmp(curname, firstname) == 1)
          printf("The first name in the list was not repeated.\n"); 
    }
    system("pause");
    return 0;
}

您只需要进行一次比较并根据该比较的结果打印您的消息。

    if (strcmp(curname, firstname) == 0 ) {
      printf("The first name in the list was repeated.\n"); 
    }
    else {
      printf("The first name in the list was not repeated.\n"); 
    }

非常清楚任何函数调用的返回值是什么总是值得的，在本例中是 strcmp。
