Thestrcat()functionappends the src string to the dest string,overwriting the terminatingnullbyte('\0')at the endofdest,and then adds a terminatingnullbyte.The strings may not overlap,and the dest string must hav
This function starts comparing the first character of each string. If they are equal to each other,it continues with the following pairs until the characters differ or until a terminating null-character is reached. 标准规定: 第一个字符串大于第二个字符串,则返回大于0的数字 第一个字符串等于第...
