int main(int argc, const char *argv[]) char a = 10; char *p = &a; /* 打印a变量存储的值 */ /* 打印a变量存储空间的首地址 */ /* 打印p变量存储的值，打印地址格式用%p */ /* 打印p变量存储空间的首地址*/ /* 打印p指向的存储空间中存储的值 */ /* 使用所有可以表示a数据值的打印方法 */ /* 使用所有可以表示a存储空间首地址的打印方法 */ return 0; }写出完整代码

Sure! Here is the complete code:

#include <stdio.h>

int main(int argc, const char *argv[])
{
    char a = 10;
    char *p = &a;
    
    printf("a variable value: %d\n", a);
    printf("a variable address: %p\n", &a);
    printf("p variable value: %p\n", p);
    printf("p variable address: %p\n", &p);
    printf("value pointed by p: %d\n", *p);
    
    printf("Printing a value using different formats:\n");
    printf("Decimal: %d\n", a);
    printf("Character: %c\n", a);
    printf("Hexadecimal: %x\n", a);
    
    printf("Printing address of a using different formats:\n");
    printf("Decimal: %lu\n", (unsigned long)&a);
    printf("Hexadecimal: %p\n", (void *)&a);
    
    return 0;
}

This code will print the values and addresses as requested in your comments.
