kaushik@IntelliBox:~/Desktop/Learn_C$ ./Practice
nNUmber is equal to : 15
nNumber is equal to : 25
0xbfcce2a4

kaushik@IntelliBox:~/Desktop/Learn_C$ ./Practice
nNUmber is equal to : 15
nNumber is equal to : 25
0xbfa25df4

kaushik@IntelliBox:~/Desktop/Learn_C$ ./Practice
nNUmber is equal to : 15
nNumber is equal to : 25
0xbfecf104

我的C代码是:

#include <stdio.h>

int main()
{
    int nNumber;
    int …
