C Program using structure

/* C program to accept Student Information (Rollno, Name, Percentage) and display same information using structure. */ 

#include<stdio.h> 

struct StudentInfo 

{ int Rno; 

char Sname[20]; 

float Percentage; 

}s1; 

void main() 

{ printf("\n Enter Student Information:"); 

printf("\n Student Roll number, Name, Percentage "); 

scanf("%d",&s1.Rno); 

scanf("%s",s1.Sname); 

scanf(“%f",&s1.Percentage); 

printf("\n Roll Number : %d",s1.Rno); 

printf("\n Student Name : %s",s1.Sname); 

printf("\n Percentage : %.2f",s1.Percentage); 

}

A structure can contain an array as its member. In the StudentInfo structure, the structure contains a string which is an array of characters. If we wish to store the marks of 4 subjects of a student, the declaration will be: 

struct StudentInfo 

{ int Rno; 

char Sname[20]; 

int marks[4]; 

float avg; 

}s; 

The members will be 

s.Rno, s.Sname, s.marks[0]…s.marks[3], s.avg
