3、你还可以用memset函数在程序开始时初始化数组。这条命令这在你已经修改了数组之后又想将它重置为全0特别有用。（变长数组适用）头文件：#include <string.h>int arr[1024];arr[5] = 67;memset(ZEROARRAY, 0, 1024); //This will reinitialize all to ZEROint a[10]={0};这样就可以了

普通字符串文字和 UTF-8字符串(因为 C11)可以初始化任何字符类型的阵列(char,signed char,unsigned char) 带前缀的宽字符串文字可用于初始化任何兼容的类型的数组(忽略 cv 资格)wchar_t u-prefixed wide string literals can be used to initialize arrays of any type compatible with (ignoring cv-qualifications...
int main(int argc, char *argv[]) { std::vector<int> integers; for (auto i = 1; i < argc; i++) { integers.push_back(std::stoi(argv[i])); } auto sum = sum_integers(integers); std::cout << sum << std::endl; }

指针方法的优点是,array的地址每次装入地址p后,在每次循环中只需对p增量操作。在数组索引方法中,每次循环中都必须根据t值求数组下标的复杂运算。 2、使用尽量小的数据类型 能够使用字符型(char)定义的变量,就不要使用整型(int)变量来定义;能够使用整型变量定义的变量就不要用长整型(long int),能不使用浮点型(flo...
Except when it is the operand of the sizeof operator or the unary & operator, or is a string literal used to initialize an array, an expression that has type ‘‘array of type’’ is converted to an expression with type ‘‘pointer to type’’ that points to the initial element of th...
