code:
将
Stu* pStu = malloc(sizeof(Stu));
改为
Stu* pStu = (Stu*)malloc(sizeof(Stu));
code
#include <stdio.h> #include <stdlib.h> typedef struct { int a; int b; }Stu; Stu* getStu(int x, int y) { Stu* pStu = (Stu*)malloc(sizeof(Stu)); pStu->a = x; pStu->b = y; return pStu; } int main() { int x = 2, y = 3; Stu *pStu = getStu(x, y); printf("%d %d ", pStu->a, pStu->b); free(pStu); return 0; }
输出
2 3 Program ended with exit code: 0
