Therefore, in order to store a string in a character array, the size of the array must be one greater than the length of the string in order to leave space for &#8216;\\0&#8217;.<\/p>\n<p>Another way to represent strings is to use pointers that point to character arrays. For example:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-type\">char<\/span> *str = <span class=\"hljs-string\">\"Hello World\"<\/span>;  <span class=\"hljs-comment\">\/\/ \u4f7f\u7528\u6307\u9488\u6307\u5411\u5b57\u7b26\u6570\u7ec4<\/span>\r\n<\/code><\/pre>\n<p>This method stores the string in the static storage area and uses a pointer to point to the first character of the string. It is important to note that strings defined using the pointer method are not editable because string constants are stored in a read-only memory area. To modify a string, it should be defined using a character array.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In C language, strings can be defined using character arrays.
