In the C language, the strcmp function can be used to compare two strings.<\/p>\n

The prototype of the strcmp function is as follows:
\nint strcmp(const char *str1, const char *str2);<\/p>\n

This function compares two strings, str1 and str2, and returns an integer value to indicate the comparison result. A return value of 0 means the two strings are equal; a value less than 0 means str1 is less than str2; a value greater than 0 means str1 is greater than str2.<\/p>\n

Here is an example of comparing strings:<\/p>\n

In the main function, there are two character arrays initialized with the values “Hello” and “World”.<\/p>\n

int result = strcmp(str1, str2);\r\n\r\nif (result == 0) {\r\n    printf(\"\u5b57\u7b26\u4e32\u76f8\u7b49\\n\");\r\n} else if (result < 0) {\r\n    printf(\"str1\u5c0f\u4e8estr2\\n\");\r\n} else {\r\n    printf(\"str1\u5927\u4e8estr2\\n\");\r\n}\r\n\r\nreturn 0;\r\n<\/code><\/pre>\n
The clouds blocked out the sun, casting a shadow over the entire field.<\/p>\n
The output shows that str1 is less than str2.<\/p>\n","protected":false},"excerpt":{"rendered":"
