The struct in C is a value type, and when a struct is assigned to another struct, the value is passed

#include <stdio.h>intMain () {structPerson {intAge ;            }; structPerson P1 = { +}; //value is passed, assigning the value of all member variables in the P1 to the corresponding member variable in the P2    structPerson p2=P1; //changes the value of the member variable of the P1 without affecting the value of the corresponding member variable in the P2P1.age = -; printf ("p1.age=%d\n", P1.age); printf ("p2.age=%d\n", P2.age); return 0;}

Results:

The struct in C is a value type, and when a struct is assigned to another struct, the value is passed
