Here, we search for the null terminator usingstrchr. The position should match the string length returned bystrlen. This example shows thatstrchrcan find the null terminator like any other character. This behav
h> #include <string.h> int main() { const char *str = "Hello, world!"; char *ptr = strrchr(str, 'o'); if (ptr != NULL) { printf("The last occurrence of 'o' is at index: %ld\n", ptr - str); } else { printf("The character 'o' is not found\n"); } return 0; ...

This code safely copies a string while ensuring null-termination. We copy one fewer character than the destination size and explicitly add the null terminator. This is a common pattern when using strncpy with fixed-size buffers. Always remember that strncpy doesn't automatically null-terminate if ...
Null-termination defect String Truncation String truncation occurs when a destination character array is not large enough to hold the contents of a string. String truncation may occur while reading user input or copying a string and is often the result of a programmer trying to prevent a ...
If you don't need null termination, usestring_view. 如果不需要0结尾,则使用string_view。 译者注:string_view是C++17引入的新特性,可以高效安全地管理字符型数组。这个数组不要求以0结尾。 Example(示例) Consider(考虑以下代码): 代码语言:javascript ...
