我想要理解valgrind日志消息并使用以下代码
#include <iostream>
int main()
{
int numbers[] = {1,2,3,4,5,6,7,8,9,10};
int length = sizeof(numbers) / sizeof(numbers[0]);
std::cout << "length: " << length << std::endl;
for (int i = 0; i < length + 10; ++i)
{
int number = numb
for line in open('file.txt'):
print(re.sub('windows', 'linux', line))
或
print(re.sub('windows', 'linux', open('file.txt').read()))
哪一个更好?有什么不同吗?
顺便说一句。使用regex操作一个巨大的字符串是一个好主意
具有以下代码:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
char *a = "abc";
int len = strlen(a);
char *b = malloc(len + 1); // + 1 for null byte
//strncpy(b, a, len) // Does not append null byte
strncat(b, a, len
