使用diff指针 [英] Use of diff pointers
问题描述
你好
Iam Niranjan ...我有一个小疑问。
void main()
{
int size;
size = sizeof(int *);
printf(" \ n size of int * ------ >%x" size);
size = sizeof(char *);
printf(\\'n char of char * ------> ;%x" size);
size = sizeof(float *);
printf(" \ n size of float * ------> %x尺寸;
}
这里所有三个都有相同的尺寸。
当这三个尺寸相同时...为什么我们需要不同类型的
指针..
plz澄清任何一个..
感谢你
Niranjan
Hello
Iam Niranjan... i have one small doubt.
void main()
{
int size;
size = sizeof(int *);
printf("\n size of int *------>%x"size);
size = sizeof(char *);
printf("\n size of char *------>%x"size);
size = sizeof(float *);
printf("\n size of float *------>%x"size);
}
here i got the same size for all three.
when all three taking the same size... why we need different type of
pointers..
plz clarify any one..
Thanking you
Niranjan

void main()
第1课:main返回int,而不是void。
当你吸收那个文件时sson,请告诉我们。

Lesson 1: main returns int, not void.
When you have absorbed that lesson, let us know.

主要返回类型和&之间的关系指针大小......?
whats the relation between main return type & pointers size...?

无论如何,因为main总是返回int。
当你明白,我们可以转到你的例子中的下一个错误
程序。在你正确地理解旧事物之前,似乎没有任何意义教你新东西

None whatsoever, because main always returns int.
When you understand that, we can move on to the next error in your example
program. There doesn''t seem to be any point in teaching you new things
until you''ve understood the old things correctly. It would be like building
a house on sand.
