Thread: Simple Sorting Algorithm

Hi People,

In my project, I've been trying to do sorting information in ascending or decsending order..

User Enters these strings:
Angelina
Barbara
Terrel
Jamel

and it orders strings as below ascending order:
Terrel
Jamel
Barbara
Angelina
_________________________
I coded and what's wrong is, while ordering in ascending it gives as a first output some ascii chars instead of entered data(ascii?-jamel-barbara-angeline)...And I couldnt solve where I did something wrong, but I guess while program doing bubble sorting, it calculates somethings wrong, here is the code

Code:

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <string.h>

struct hospital{
	char doctor[30];} hospital;

int size=0;

int menu();
void doctor(struct hospital* x, struct hospital temp);
struct hospital temp;


int main(){

	struct hospital* patient;
	
	int i=0;
	int choice;
	printf("Please give the number of data records:\n");
		scanf("&#37;d",&size);

	patient=malloc(size*sizeof(hospital));

	printf("Please give %d patient records in the form:\n",size);
	while(i!=size){

		printf("Enter the doctor's name:\n");
			scanf("%s",patient[i].doctor);
					i++;
	}

	printf("The Patient Information entered is shown below:\n");
	i=0;

	
		choice=menu();

		switch (choice){
			if(choice==0){return 0;}
		case 1:
			doctor(patient, temp);
			break;
		}
		return 0;
}

int menu(){
	int choice2;

	printf("\nPlease give a Sorting Code according to menu below to Exit Press \"0\":\n");
	printf("1-Surname ascending\n");
		scanf("%d",&choice2);
		return choice2;
}

void doctor(struct hospital* x, struct hospital temp){ //here trying to do kind of bubble sort to sort in ascending order.
	int i=0;
	int j=0;
	for(i=0 ; i<size+1 ; i++){
		for(j=0 ; j<size ; j++){
			if((strcmp(x[j].doctor,x[j+1].doctor) < 0)){
				temp=*(x+j);
				*(x+j) = *(x+j+1);
				*(x+j+1) = temp;
			}
		}
	}
	i=0;

		
	
	i=0;
	while( i != size ){
		printf("%10s\n", x[i].doctor);
		i++;
	}
}
