In the C language, the strcmp function can be used to compare the sizes of two strings. This function has three possible return values.<\/p>\n

    \n
  1. If the return value is less than 0, it means the first string is smaller than the second string.<\/li>\n
  2. If the return value is 0, it means that the two strings are equal.<\/li>\n
  3. If the return value is greater than 0, it means the first string is greater than the second string.<\/li>\n<\/ol>\n

    The code example is shown below:<\/p>\n

    #include<\/span> <stdio.h><\/span><\/span>\r\n#include<\/span> <string.h><\/span><\/span>\r\n\r\nint<\/span> main<\/span>()<\/span> {\r\n    char<\/span> str1[100<\/span>], str2[100<\/span>];\r\n    printf<\/span>(\"\u8f93\u5165\u7b2c\u4e00\u4e2a\u5b57\u7b26\u4e32: \"<\/span>);\r\n    scanf<\/span>(\"%s\"<\/span>, str1);\r\n    printf<\/span>(\"\u8f93\u5165\u7b2c\u4e8c\u4e2a\u5b57\u7b26\u4e32: \"<\/span>);\r\n    scanf<\/span>(\"%s\"<\/span>, str2);\r\n\r\n    int<\/span> result = strcmp<\/span>(str1, str2);\r\n    if<\/span> (result < 0<\/span>) {\r\n        printf<\/span>(\"%s \u5c0f\u4e8e %s\\n\"<\/span>, str1, str2);\r\n    } else<\/span> if<\/span> (result == 0<\/span>) {\r\n        printf<\/span>(\"%s \u7b49\u4e8e %s\\n\"<\/span>, str1, str2);\r\n    } else<\/span> {\r\n        printf<\/span>(\"%s \u5927\u4e8e %s\\n\"<\/span>, str1, str2);\r\n    }\r\n    \r\n    return<\/span> 0<\/span>;\r\n}\r\n<\/code><\/pre>\n
    In the above code, we used the strcmp function to compare two strings and printed different results based on the return value.<\/p>\n","protected":false},"excerpt":{"rendered":"
