Why does this program prints many times the red point?
thanks in advance...
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

struct myInfo{
	char my_name[81];
	char my_phone[81];
	char my_street[81];
	char my_email[81];
};

struct Info{
	char name[81];
	char phone[81];
	char street[81];
	char email[81];
};

// It prints name, phone, address, and e-mail.
void print(struct Info info){
	printf("Diagnostic.\n\n");
}

int main(void){
	int choice;
	char buf[6];
	FILE *infile;
	struct Info info;
	struct myInfo myinfo;

		print(info);
		// Opening the file.
		infile = fopen("file.txt","r+");
		
		// Check if the file exist.
		if(infile==NULL){
			printf("Error :(\n");
			exit(1);
		}
		
		// Reading the file. Read: name, phone, address and e-mail. It read and prints, reads prints, reads prints...
		while(fscanf(infile,"%s %s %s %s", info.name, info.phone, info.street, info.email) != EOF){
			print(info);	
		}

		printf("If you want to put a new contact please type: 1\n");
		printf("To exit please type: 0\n");
		
		scanf("%d", &choice);

		if(choice==1){ //Giving info for a new contact.
			printf("Please type your name:");
			scanf("%s", myinfo.my_name);

			printf("Please type your phone:");
			scanf("%s", myinfo.my_phone);
			
			printf("Please type your street:");
			scanf("%s", myinfo.my_street);

			printf("Please type your e-mail:");
			scanf("%s", myinfo.my_email);

			//These are the info the user typed.
			printf("Your name is: %s\n", myinfo.my_name);
			printf("Your phone is: %s\n", myinfo.my_phone);
			printf("Your name is: %s\n", myinfo.my_street);
			printf("Your name is: %s\n", myinfo.my_email);

			//Puting them into the file, using fprintf.
			fprintf(infile,"%s %s %s %s", myinfo.my_name, myinfo.my_phone, myinfo.my_street, myinfo.my_email);
		}else if(choice==0){
			printf("Are you sure yes/no?\n");
			scanf("%s", buf);
			if(buf=="yes"){
				exit(1);
			}else{
				printf("I was hoping to come back!\n");
			}
			
		}

		fclose(infile);

	return 0;
