Explanation / Answer

Write a C program that will read and store the details of a list of students in the format below:

       ID                   NAME                     MARKS

Which will produce the following respective output

1.Alphabetical list of Names, ID’s and Marks.

2.List sorted on ID’s

3.List sorted on Marks

//Program

#define N 5
#include<stdio.h>
#include<string.h>
int main()
{
char names[N][30],marks[N][10];
char id[N][12],temp[30];
int i,j;
/* Reading Student Details */
printf("Enter Student ID NAME and MARKS ");
for(i = 0; i<N; i++)
scanf("%s %s %s",id[i],names[i],marks[i]);

/* Alphabetical Ordering of Names */
for(i=0; i<N-1; i++)
for(j=0; j<N-i-1; j++)
if(strcmp(names[j],names[j+1])>0)
{ strcpy(temp,names[j]);
strcpy(names[j], names[j+1]);
strcpy(names[j+1], temp);
/* Swapping of marks */
strcpy(temp,marks[j]);
strcpy(marks[j], marks[j+1]);
strcpy(marks[j+1], temp);

/* Swapping of ID’s */
strcpy(temp,id[j]);
strcpy(id[j], id[j+1]);
strcpy(id[j+1], temp);
}
printf("ALPHABETICAL LIST OF ID NAME & MARKS");
for(i=0;i<N;i++)
printf("%s %s %s ", id[i], names[i], marks[i]);
return 0;
}

Write a C program which will read a line of text and rewrite it in the alphabetical order.

//Program

/* Reading terminated string */
scanf("%[^ ]s", text);

while(text[i]!= '')

while(1) /* Finding space terminated strings */
{ if(text[i]==' '|| text[i]=='')
break;
Word[j++] = text[i++];

k++;
if(text[i]!='')
i++;
}
for(k--; k>=0; k--)
