C programming simple issue .Asking two Inputs on same line

Question

Hello i am beginner in programmin. I have simple issue. When i take user input. I was asked Enter Your Age: then after entering age i was asked(problem is here: why it's executing two linesc) "Enter c for city and v for village: Enter 'h' for healthy and 'p' for poor health: "

and cursor comes after health:

It should ask for "Enter c for city and v for village:" first. I have tried alot. Please help me

int main(){
int age;
char sex;
char location;
char health;

printf("Enter Your Age: ");
scanf("%d",&age);
printf("Enter c for city and v for village: ");
scanf("%c", &location);
printf("Enter 'h' for healthy and 'p' for poor health: ");
scanf("%c", &health);
printf("Enter 'm' for male and 'f' for female: ");
scanf("%c", &sex);


if(age>=25 && age<=35){

  printf("hello ahmed ");
}
    else{
         printf("Sorry You Cannot Be Insured ");
}


getch();
return 0;

}

The correct solution depends on whether you are using C or C++. They are not the same language! — Christian Hackl

It seems when you enter your age, the 'enter' remains in the buffer and gets read into location.

printf("Enter Your Age: ");
scanf("%d",&age); 
printf("Enter c for city and v for village: ");
scanf("\n%c", &location); // add this line to ignore the newline character.

EDIT: fflush() removed because it seems it works only for output streams and not input. IMO Better is to first read the newline character and then the actual location character.

instead of using getch(), it's safer to use fflush(stdin)

@Abishek result is the same

@AbhisshekBansal Indeed the behaviour of fflush on input streams is not standardized (ie, it's not guaranteed to work), sorry for that. See this SO question for a more thorough explanation and an albeit nonportable workaround. But your workaround works too, +1

Another option is to

scanf(" %c", &location);

include a space before the %c for it to ignore the white space or new line.
