When storing the string values in the already initialized array, the assignment operator is not permitted, and special memory copying functions should be employed likestrcpy. #include<stdio.h>#include<stdlib.h>#include<string.h>#defineMAX_LENGTH 100#defineNUM_STRINGS 10intmain(){chararr[NUM_STRI...

#include<stdio.h> #define MAX 50 int main() { char str[MAX]; fgets(str, MAX, stdin); printf(âString is: \nâ); puts(str); return 0; } Output: UnstopString is:Unstop Explanation: This program defines a character array of a maximum size of 50, which stores a ...
char *pcStr = (char *)malloc(sizeof(char) * 10);strcpy(pcStr, "Hello");printf("The copied string is %s\n", pcStr);free(str);（3）使用预处理器宏 使用预处理器宏可以避免重复编写相同的代码，从而提高代码的可读性和可维护性。例如：#define STR_LEN 10 char pcStr[STR_LEN];5、结论 C语言...

A structure can be created inside as well as outside the main method. To define a structure, the keyword ‘struct’ is used as shown in the below program. The size of the structure would be the sum of the storage size required by every variable. ...
■用C预处理器指令#define和ANSIC的const修饰符创建符号常量。 本章重点介绍输入和输出。与程序交互和使用字符串可以编写个性化的程序,本章将详细介绍C语言的两个输入/输出函数:scanf()和printf)。学会使用这两个函数,不仅能与用户交互,还可根据个人喜好和任务要求格式化输出。最后,简要介绍一个重要的工具—C预处理...
C语言代码很简洁,里面用到了不少的英文缩写。如果不了解这些缩写,程序的第一行都难以理解,更何况后续的学习。举个例子,部分初学者有可能把第一行的stdio写成studio,还不容易察觉。下面列出一些常见的英文缩写,便于初学者理解和记忆,做到事半功倍。 初学者可以在即刻编程的云教室里面直接运行C语言程序,避免折腾环境 ...
