C Program to sort a customer list in the alphabetical list.
#include<stdio.h>
#include<conio.h>
#define CUSTOMERS 10
void main()
{
char first_name[20][10], second_name[20][10], surname[20][10], name[20][20], telephone[20][10], dummy[20];
int i,j;
printf("Input names and telephone numbers");
printf("?");
for(i=0;i<CUSTOMERS;i++)
{
scanf("%s %s %s %s", first_name[i],second_name, surname[i], telephone[i]);
strcpy(name[i], surname[i]);
strcat(name[i], ",");
dummy[0]=first_name[i][0];
dummy[1]=' ';
strcat(name[i],dummy);
stcat(name[i],".");
dummy[0]=second_name[i][0];
dummy[1]=' ';
strcat(name[i],dummy);
}
for(i=1;i<=CUSTOMERS-1;i++)
for(j=1;j<=CUSTOMERS-1;j++)
if(strcmp(name[j-1], name[j])>0)
{
strcpy(dummy,name[j-1]);
strcpy(name[j-1],name[j]);
strcpy(name[j],dummy);
strcpy(dummy,telephone[j-1]);
strcpy(telephone[j-1],telephone[j]);
strcpy(telephone[j],dummy);
}
printf("CUSTOMERS LIST IN ALPHABETICAL ORDER");
for(i=0;i<CUSTOMERS;i++)
printf("%-20st%-10s",name[i],telephone[i]);
}
Output
