Answer 1

#include <stdio.h>


void display(char array[][30],int Marks[], int n)
{
  for(int i=0; i<n; i++){
    printf("\n%10d%10s, \tMarks = %d ", i+1,array[i],Marks[i]);
  }
  printf("\n");
}




int main()
{
	char Names[][30] = { "ABC", "LMN", "JKL","XYZ","QAZ","QWERT" };
    int n = sizeof(Names) / sizeof(Names[0]);
  	int Marks[] = {78, 65, 87, 94, 60, 57};
    int i,j;
    char temp[30];
    int u;




  printf("Before Sorting: ");	  display(Names,Marks,n);  




  	for(int i=0; i<n; i++)
  	{
  		for(int j=0; j<n-1-i; j++)
		{
      		if(strcmp(Names[j], Names[j+1]) > 0)
			  {
        		strcpy(temp, Names[j]);
        		u = Marks[j];
		        strcpy(Names[j], Names[j+1]);
        		strcpy(Names[j+1], temp);
        		Marks[j] = Marks[j+1];
        		Marks[j+1] = u;
      		}
    	}
  	}




  printf("\nAfter Sorrting Alphabatically: ");
  display(Names,Marks,n);  








  	for(int i=0; i<n; i++)
  	{
  		for(int j=0; j<n-1-i; j++)
		{
      		if(Marks[j]<Marks[j+1])
			  {
        		u = Marks[j];
        		Marks[j] = Marks[j+1];
        		Marks[j+1] = u;
        		strcpy(temp, Names[j]);
        		strcpy(Names[j], Names[j+1]);
        		strcpy(Names[j+1], temp);
      		}
    	}
  	}
  printf("\nAfter Sorrting using Marks: ");
  display(Names,Marks,n);  
  
    return 0;
