the first time enter the "while loop" and the second no! Why?
When i type first time 1 the printf appeared, but the second time i typed 1 there where no printf...can anyone help me?
Code:
#include <stdio.h>
#include <stdlib.h>
struct Info{
char name[81];
int age;
char email[81];
int c;
};
int main(void){
FILE* infile;
struct Info info;
infile = fopen("my_file.txt","r+"); // pos: r, w, a, r+, w+, a+
if(infile ==NULL){
printf("File does not exist.\n");
exit(1);
}else{
printf("Please type 1 to see the statistics.\n");
printf("Please type 2 to add a new contact.\n");
printf("Plesase type 0 to exit.\n");
scanf("%d", &info.c);
while(1){
if(info.c == 1){
while(fscanf(infile,"%s %d %s", info.name, &info.age, info.email) != EOF){
printf("\tName: %s\n", info.name);
printf("\tAge: %d\n", info.age);
printf("\tE-mail: %s\n\n", info.email);
}
}else if(info.c == 2){
printf("New name:\n");
scanf("%s", info.name);
printf("New age:\n");
scanf("%d", &info.age);
printf("New e-mail:\n");
scanf("%s", info.email);
fprintf(infile,"%s %d %s", info.name, info.age, info.email);
fclose(infile);
infile = fopen("my_file.txt","r+");
}else{
exit(0);
}
printf("Please type 1 to see the statistics.\n");
printf("Please type 2 to add a new contact.\n");
printf("Plesase type 0 to exit.\n");
scanf("%d", &info.c);
}
}
fclose(infile);
return 0;
}
