There are several ways in C language to add characters to a string.<\/p>\n

    \n
  1. Concatenate two strings.<\/li>\n
  2. concatenate two strings<\/li>\n<\/ol>\n
    #include<\/span> <string.h><\/span><\/span>\r\n\r\nchar<\/span> str1[20<\/span>] = \"Hello\"<\/span>;\r\nchar<\/span> str2[] = \" World!\"<\/span>;\r\nstrcat<\/span>(str1, str2);   \/\/ \u5c06str2\u8ffd\u52a0\u5230str1\u7684\u672b\u5c3e<\/span>\r\n<\/code><\/pre>\n
      \n
    1. By using pointer operations: you can access each character of a string and insert new characters when necessary.<\/li>\n<\/ol>\n
      char<\/span> str[20<\/span>] = \"Hello World!\"<\/span>;\r\nint<\/span> index = 5<\/span>;\r\nchar<\/span> newChar = ','<\/span>;\r\n\r\n\/\/ \u5728\u7d22\u5f15\u4f4d\u7f6e\u63d2\u5165\u65b0\u5b57\u7b26<\/span>\r\nint<\/span> length = strlen<\/span>(str);\r\nfor<\/span> (int<\/span> i = length; i >= index; i--) {\r\n    str[i + 1<\/span>] = str[i];\r\n}\r\nstr[index] = newChar;\r\n<\/code><\/pre>\n
        \n
      1. Inserting new characters directly at an index position using index operations on a character array.<\/li>\n<\/ol>\n
        char<\/span> str[20<\/span>] = \"Hello World!\"<\/span>;\r\nint<\/span> index = 5<\/span>;\r\nchar<\/span> newChar = ','<\/span>;\r\n\r\n\/\/ \u5728\u7d22\u5f15\u4f4d\u7f6e\u63d2\u5165\u65b0\u5b57\u7b26<\/span>\r\nint<\/span> length = strlen<\/span>(str);\r\nfor<\/span> (int<\/span> i = length; i >= index; i--) {\r\n    str[i + 1<\/span>] = str[i];\r\n}\r\nstr[index] = newChar;\r\n<\/code><\/pre>\n
        It is important to make sure that the target character array has enough space to store new characters when performing string operations. Additionally, when using pointer operations, be mindful of the position of the string’s null terminator \\0 and ensure it is in the correct place.<\/p>\n","protected":false},"excerpt":{"rendered":"
