例如,使用 -fno-builtin 选项可以告诉 GCC 不要将某些函数作为内置函数处理。这个选项可以应用于特定的函数,也可以应用于所有的内置函数。 例如,如果您想要禁用对 printf 函数的内置处理,可以使用以下命令: gcc -fno-builtin-printf your_file.c -o your_program 这将告诉 GCC 不要将 printf 函数作为内置函数处...

String API in C To include the string input-output operations in your program, you can add the header file definition: #include <string.h> where the strings are known to be NULL terminated character arrays. You can declare a string as follows in the C language ...

答案解析 查看更多优质解析 解答一 举报 char str[100]=”program”; str+1就是"program”中的字符'r'的地址,strlen的规则是从传入的地址起计数,直到找到'\0'为止('\0'不计在内),所以表达式strlen(str+1)的值是6.(字符r,o,g,r,a,m) 解析看不懂?免费查看同类题视频解析查看解答 ...
Disclaimer: The strlen function rarely lies on the critical path of the program, and if it is, you should store the string length in an integer variable (Pascal-style strings). This article should be viewed as an exercise in code optimization, not as a recommendation for everyday programming...
