Question

我不知道为什么字符串中的输入大写字母会更改为随机代码

#include<stdio.h>
#include<string.h>
#define length 100
int main()
{
   int count;
   char word[length];
   printf("Please input your word =");
   scanf("%s", &word);
   count=strlen(word);
   int i;
   for(i=0;i<=count;i++)
   {
        if(word[i]>=97||word[i]<=122)
        {
           word[i]+= -32;
        }
        printf(" %c",word[i]);
   }
   return 0;
}

Answer 1

变化：

if(word[i]>=97||word[i]<=122)

要：

if(word[i]>=97 && word[i]<=122)

Answer 2

你应该在条件中使用AND运算符而不是OR运算符。

if(word[i]>=97 && word[i]<=122)    //to specify small character region's upper AND lower bound

可能会尝试使用

word[i] -= 32; //for simplicity

Answer 3

|| -------“＆amp;＆amp;

#include<stdio.h>
#include<string.h>
#define length 100
int main()
 {
    int count;
    char word[length];
    printf("Please input your word =");
    scanf("%s", word);
    count=strlen(word);
    int i;
    for(i=0;i<count;i++)
       {
           if(word[i]>=97&&word[i]<=122)
             {
                word[i]+= -32;
             }
           printf(" %c",word[i]);
  }
    return 0;
}

为什么我不能将所有单词转换为大写C.
