Question

Consider:

typedef struct { int x; int y; } Point; Point p; Point* pp; Assign the coordinates (10, 20) to point p.

choose the following Multiple choice question

1.) p[x] = 10; p[y] = 20;

2.) p->x = 10; p->y = 20;

3.) p(x) = 10; p(y) = 20;

4.) p.x = 10; p.y = 20;

Answer 1

answer)4.) p.x = 10; p.y = 20;

p is pointer variable pointing to structure Point. x and y are variables in structure.p.x is used to access x variable in structure Point and p.y is used to access y variable in structure Point.

#include <stdio.h>
typedef struct { int x; int y; } Point;Point p;
int main()
{
p.x=10;
p.y=20;
printf("%d %d",p.x,p.y);

return 0;
}

10 20 ... Program finished with exit code 0 Press ENTER to exit console. I
