c_cpp 指针迭代与C中的int指针

Posted 2021-05-14

#include <stdio.h>
#include <stdlib.h>


int main(int argc, char const *argv[])
{
	int* nums = malloc(sizeof(int) * 5);
	int* numsEnd = nums + 5;
	for (int* ptr = nums; ptr != numsEnd ; ptr++)
	{
		*ptr = 3;
	}
		for (int* ptr = nums; ptr != numsEnd ; ptr++)
	{
		printf("The num is %d\n", *ptr);
	}
	return 0;
}
