How to Copy and Compare Structure Variables?

Two variables of the same structure type can be copied the same way as ordinary variables. If persona1 and person2 belong to the same structure, then the following statements Are valid. person1 = person2; person2 = person1; C does not permit any logical operators on structure variables In case, we need to compare them, we may do so by comparing members individually. person1 = = person2 person1 ! = person2 Statements are not permitted. Ex: Program for comparison of structure variables struct class { int no; char name [20]; float marks; } main ( ) { int x; struct class stu1 = { 111, “Rao”, 72.50}; struct class stu2 = {222, “Reddy”, 67.80}; struct class stu3; stu3 = stu2; x = ( ( stu3.no= = stu2.no) && ( stu3.marks = = stu2.marks))?1:0; if ( x==1) { printf (“ \n student 2 & student 3 are same \n”); printf (“%d\t%s\t%f  “ stu3.no, stu3.name, stu3.marks); } else printf ( “\n student 2 and student 3 are different “); } Out Put: Student 2 and student 3 are same 222 reddy 67.0000
