To access the last character of a string in C, we first need to find the last character index using thestrlen(str)-1and pass it to the[]notation. The strlen() function returns the total number of characters in a
In C language,/0indicates the string ending. Here is an example: #include<stdio.h>#include<string.h>intmain(){charname[6]="lahari";name[strlen(name)-1]='\0';// removing the last character iprintf("%s\n",name);} Output:
cJSON_Number (check with cJSON_IsNumber): Represents a number value. The value is stored as a double in valuedouble and also in valueint. If the number is outside of the range of an integer, INT_MAX or INT_MIN are used for valueint. cJSON_String (check with cJSON_IsString): Rep...
以下示例合并了对消息的签名和编码,并解码已签名的消息并验证签名。 这两个作通常位于单独的程序中。 编码示例将创建编码的消息,将其保存到磁盘文件,或者以某种其他方式将其发送到其他用户。 解码示例将收到编码的消息,对其进行解码,并验证签名。 此处已合并这两个过程,以显示这两个过程正常工作。
