Why is not printing names ??

#include <stdio.h> #include <stdlib.h> #include <string.h> // The student structure union Student { char* name ; int roll_number; float marks; }; int main() { int i = 0, n = 5; union Student student[n]; //Students data student[0].name = "Kapil"; student[0].roll_number = 1; student[0].marks = 73.6; student[1].name = "Vikas"; student[1].roll_number = 2; student[1].marks = 78.3; student[2].name = "Ajay"; student[2].roll_number = 3; student[2].marks = 87.4; // Print the Students information printf("Student Details:\n\n"); for (i = 0; i < n; i++) { printf("\tName = %s\n", &student[i].name); printf("\tRoll Number = %d\n", &student[i].roll_number); printf("\tTotal Marks = %f\n\n", &student[i].marks); } return 0; }

You can't use a union. Unions only allow for one attribute to be held at one time. You can't assign all three cause each assigment will overwrite the last.

Use struct instead of union. And remove & in loop print statements.. printf("Student Details:\n\n"); for (i = 0; i < n; i++) { printf("\tName = %s\n", student[i].name); printf("\tRoll Number = %d\n", student[i].roll_number); printf("\tTotal Marks = %f\n\n", student[i].marks); } since you added only 3 values, use n=3

Yes. Union only holds one last attribute value stored by overwriting..
