C Program to copy a structure in C
Using Structure - C Programming
Program to copy a structure in C.
We can use the below methods to copy one structure to another structure in C language.
• We can copy using direct assignment of one structure to another structure or
• We can use C inbuilt function "memcpy()" or
• We can copy by individual structure members.
#include <stdio.h>
#include <string.h>
struct student
{
int id;
char name[30];
floatpercentage;
};
int main()
{
int i;
struct student record1={1, "Mahi", 96.5};
struct student record2, *record3, *ptrl, record4;
printf("Records of STUDENT1 record1 structure \n");
printf(" Id: %d\n Name: %s\n Percentage: %f\n", record1.id, record1.name, record1.percentage);
/* 1sd method to copy whole structure to another structure */
record2= record1;
printf("\nRecords of STUDENT1‒Direct copy from ""record1 \n");
printf(" Id: %d\n Name: %s\n Percentage: %f\n", record2.id, record2.name, record2.percentage);
/* 2nd method to copy using memcpy function */
ptrl=&record1;
memcpy(record3, ptrl, sizeof(record1));
printf("\nRecords of STUDENT1‒copied from record1"\"using memcpy \n");
printf(" Id: %d\n Name: %s\n Percentage: %f\n", record3‒> id, record3‒>name, record3‒>percentage);
/* 3rd method to copy by individual members */
printf("\nRecords of STUDENT1‒Coping individual *\ "members from record1 \n");
record4.id=record1.id;
strcpy(record4.name, record1.name);
record4.percentage record1.percentage;
printf(" Id: %d\n Name: %s\n Percentage: %f\n", record4.id, record4.name, record4.percentage);
return 0;
}
OUTPUT
Records of STUDENTI ‒ record structure
Id : 1
Name : Mahi
Percentage : 96.500000
Records of STUDENTI - Direct copy from record1
Id : 1
Name : Mahi
Percentage : 96.500000
Records of STUDENT1 ‒ copied from record1 using memcpy
Id : 1
Name : Mahi
Percentage : 96.500000
Records of STUDENT1‒Coping individual members from recordl
Id : 1
Name : Mahi
Percentage : 96.500000
