复制代码 全局变量:可以定义全局变量,在函数内部修改全局变量的值,从而实现多个值的返回。 #include <stdio.h> int value1, value2; void getValues() { value1 = 10; value2 = 20; } int main() { getValues(); printf("Value 1: %d\nValue 2: %d\n", value1, value2); return 0; } 复制...
'); if (pvstrs == NULL) { // 没有参数部分,直接返回 return 0; } // 创建字符串的副本进行解析 char* pvstrsCopy = strdup(pvstrs + 1); if (pvstrsCopy == NULL) { // 内存分配失败 return -1; } // 通过等号来分析,将每个参数 参数名放入params, value放在values char* iter = strtok...
#include<stdio.h>#defineN_VALUES5float values[N_VALUES];float*vp;intmain(){for(vp=&values[N_VALUES];vp>&values[0];vp--){*--vp=0;}return0;} 看这串代码,便是利用指针的关系运算来实现对数组的初始化,一开始vp=5,然后每一轮循环都会-1,然后从第五个元素开始逐步进行初始化,五次循环之后,...

return 0; } 可以看到 C 语言的入口函数跟 Java 的类似吧,都是以main来定义的入口,接下来我们讲解一下上面这段程序的意思: (1)程序的第一行#include <stdio.h>是预处理器指令,告诉 C 编译器在实际编译之前要包含 stdio.h 文件。 (2)下一行 /.../ 将会被编译器忽略,这里放置程序的注释内容。它们被称...
输出:values of a = 10,bc = 30 and g = 40 形式参数 函数的参数,形式参数,被当作该函数内的局部变量,如果与全局变量同名它们会优先使用。下面是一个实例: int sumA(int a, int b) { printf("value of a in sum() = %d\n", a);
