In the C language, although there is no built-in string type, you can use character arrays to represent strings. Here are several common ways to use strings:<\/p>\n

    \n
  1. Store the string in a character array.<\/li>\n<\/ol>\n
    char<\/span> str[10<\/span>]; \/\/ \u5b9a\u4e49\u4e00\u4e2a\u957f\u5ea6\u4e3a10\u7684\u5b57\u7b26\u6570\u7ec4<\/span>\r\nstrcpy<\/span>(str, \"Hello\"<\/span>); \/\/ \u5c06\u5b57\u7b26\u4e32\u590d\u5236\u5230\u5b57\u7b26\u6570\u7ec4\u4e2d<\/span>\r\nprintf<\/span>(\"%s\\n\"<\/span>, str); \/\/ \u8f93\u51fa\u5b57\u7b26\u4e32<\/span>\r\n<\/code><\/pre>\n
      \n
    1. Store strings using character pointers.<\/li>\n<\/ol>\n
      char<\/span> *str; \/\/ \u5b9a\u4e49\u4e00\u4e2a\u5b57\u7b26\u6307\u9488<\/span>\r\nstr = \"Hello\"<\/span>; \/\/ \u6307\u9488\u6307\u5411\u5b57\u7b26\u4e32\u5e38\u91cf<\/span>\r\nprintf<\/span>(\"%s\\n\"<\/span>, str); \/\/ \u8f93\u51fa\u5b57\u7b26\u4e32<\/span>\r\n<\/code><\/pre>\n
        \n
      1. Manipulate strings using character arrays and library functions related to strings, such as strcpy, strcat, strlen, etc.<\/li>\n<\/ol>\n
        char<\/span> str1[10<\/span>] = \"Hello\"<\/span>;\r\nchar<\/span> str2[10<\/span>] = \"World\"<\/span>;\r\nchar<\/span> str3[20<\/span>]; \/\/ \u5b9a\u4e49\u4e00\u4e2a\u8db3\u591f\u5927\u7684\u5b57\u7b26\u6570\u7ec4\u6765\u5b58\u50a8\u8fde\u63a5\u540e\u7684\u5b57\u7b26\u4e32<\/span>\r\n\r\nstrcpy<\/span>(str3, str1); \/\/ \u5c06str1\u590d\u5236\u5230str3\u4e2d<\/span>\r\nprintf<\/span>(\"%s\\n\"<\/span>, str3); \/\/ \u8f93\u51faHello<\/span>\r\nstrcat<\/span>(str3, str2); \/\/ \u5c06str2\u8fde\u63a5\u5230str3\u540e\u9762<\/span>\r\nprintf<\/span>(\"%s\\n\"<\/span>, str3); \/\/ \u8f93\u51faHelloWorld<\/span>\r\nprintf<\/span>(\"%d\\n\"<\/span>, strlen<\/span>(str3)); \/\/ \u8f93\u51fa\u5b57\u7b26\u4e32\u7684\u957f\u5ea6<\/span>\r\n<\/code><\/pre>\n
