数组超出界限 [英] Array Out Of Boundaries

问题描述

int main（）

{


int i，j;

int k [] = {1,2 ，3,4,5};

k [5] = 50;

printf（"％d％d"，i，j）;

}


这个程序编译正常，结果是-858993460 50

我无法找到为什么打印上述值。请求帮助

这个

k [5] = 50;

printf（"％d％d" ，我，j）;

}

我无法找出为什么打印上述值。请求帮助

就此而言。

嘿，索引从0开始。所以数组中有5个元素

从0到4开始。所以k [5 ]将是阵列之外的第6个元素

阵列。

这是理解的。但是，为什么j在这里打印价值50所有时间或你所分配的价值。

这是明白的。但是j怎么来这里打印值50

您分配的时间或价值。

你期望j有什么价值？

int main()
{

int i,j;
int k[]={1,2,3,4,5};
k[5]=50;
printf("%d %d",i,j);
}

This program is compiling fine and the result is -858993460 50
I am unable to find why this is printing the above value. Request help
on this

Hey, the indexing starts from 0. So you have 5 elements in the array
starting from 0 to 4. So k[5] would be 6th element outside the bounds
of the array.

That is understood .But how come j is printing the value 50 here all
the time or what ever value you are assigning.

What value did you expect j to have?
