Question

Declare an array of 40 student_t structures, and write a code segment that displays on separate lines the names (last name, first name) of all the students in the list. IN C 

Answer 1

Hi there,

The code :

#include<stdio.h>
typedef struct{
   char first[50];   //to store first name
   char last[50];   //to store last name
}student_t;
int main()
{
   student_t stud[40];
   for(int i=0;i<40;i++)
   {
       printf("\nEnter the first name for student %d : ",i+1);
       scanf("%s",stud[i].first);   //input first name
       printf("\nEnter the last name for student %d : ",i+1);
       scanf("%s",stud[i].last);   //input last name
       printf("\n");
   }  
   for(int i=0;i<40;i++)
   {
       printf("\n%s %s",stud[i].first,stud[i].last);   //print the complete name
   }
   printf("\n");
   return 0;
}      

The code(screenshot) :

1 #include<stdio.h> 2 typedef struct{ char first[50]; //to store first name, 4 char_last[50]; //to store last name 5}student t; 6 int main() 7{ student_t stud[40]; for(int i=0;i<40;i++) 10 12 printf("\nEnter the first name for student %d : ",i+1); 'scanf("%s", stud[i].first); //input first name printf("\nEnter the last name for student %d : ",i+1); scanf("%s", stud[i].last); //input last name printf("\n"); for(int i=0;i<40; i++) printf("\n%s %s", stud[i].first, stud[i].last); //print the complete nameli printf("\n"); return 0; 22 23 }

The output(screenshot) :(4 inputs only)

Enter the first name for student 1 : asd Enter the last name for student 1 : af Enter the first name for student 2 : gr Enter the last name for student 2 : yuk Enter the first name for student 3 : dgf Enter the last name for student 3 : ghm Enter the first name for student 4 : sg Enter the last name for student 4 : guk asd af gr yuk dgf ghm sg guk

Thank you.

Happy Coding :)
