如何测试c++中printf函数的稳定性和准确性

???C++?printf??????????,???????????????????????????????:

1. ??????:??printf???????????????,??????????????????:

#include 

int main() {
    int a = 42;
    float b = 3.14f;
    char c = 'A';
    const char* s = "Hello, World!";
    
    printf("Integer: %d\n", a);
    printf("Float: %.2f\n", b);
    printf("Character: %c\n", c);
    printf("String: %s\n", s);
    
    return 0;
}

2. ?????:??printf??????,???????????????:

#include 

int main() {
    int a = 42;
    float b = 3.14f;
    
    printf("Width: ]\n", a);
    printf("Precision: %.2f\n", b);
    printf("Fill character: d\n", a);
    
    return 0;
}

    printf("Minimum int: %d\n", min_int);
    printf("Maximum int: %d\n", max_int);
    printf("Null pointer: %s\n", (null_ptr ? null_ptr : "NULL"));
    
    return 0;
