Answer 1

#include<stdio.h>
#include<stdlib.h>
int main()
{
   //VARIABLE DECLARATIONS
   char names[1000][30],temp[30];
   int userID[1000],mark[1000];
   int i,n;
   //ASK USER FOR NUMBER OF STUDENTS TO INPUT
   printf("\n Enter the number of students want to enter");
   gets(temp); //read the nu,mber using gets()
   n=atoi(temp); //assign it to n by using atoi(), which converts string to integer
   //loop to read n number of students
   for(i=0;i<n;i++)
   {
       printf("\n Enter the name of student %d:",i+1);
       gets(names[i]); //read the name
              
       printf("\n Enter ID for student %d:",i+1);
       gets(temp); //read the student is
       userID[i]=atoi(temp); //convert to integer using atoi()
      
       printf("\n Enter mark for student %d:",i+1);
       gets(temp);//read the mark
       mark[i]=atoi(temp); //convert to integer wsing atoi()
   }
  
   printf("\n NAME\t\tUSERID\tMARKS");
   //display the details
   for(i=0;i<n;i++)
   printf("\n%s\t%d\t%d",names[i],userID[i],mark[i]);
}
