Question

Given details (like roll number, name and marks) of 5 students as an input, read all the details into Student structure and display the content.

Input:

1 Jack 72.12

2 Tom 42.42

3 Robert 72.12

4 Michael 72.12

5 James 72.12    

    where:

• All lines represent Roll number, Name and Marks respectively.

Output:

1 Jack 72.12

2 Tom 42.42

3 Robert 72.12

4 Michael 72.12

5 James 72.12

not sure why my output is off.

#include <stdio.h>
struct student
{
char name[30];
int roll;
float marks;
} s[10];
int main()
{
int i;
for(i=0; i<5; i++)
{
s[i].roll = i;
scanf("%s",s[i].name);
scanf("%f",&s[i].marks);
  
}
  
for(i=0; i<5; i++)
{
  
puts(s[i].name);
printf(" %.2f",s[i].marks);
}
return 0;
}

Answer 1

correct code is:

#include <stdio.h>
struct student
{
char name[30];
int roll;
float marks;
} s[10];
int main()
{
int i;
for(i=0; i<5; i++)
{
s[i].roll = i;
scanf("%s",&s[i].name); //added refrence sighn before s
scanf("%f",&s[i].marks);
  
}
  
for(i=0; i<5; i++)
{
printf("%d",i+1); //added a line to print roll no
//puts(s[i].name); //instead using puts used printf statement to print name
printf(" %s ",s[i].name);
printf(" %.2f ",s[i].marks);
printf("\n");
}return 0;}
