program to print the word starting with first character

Question

This code should print the word starting with input character but something wrong with it.

I have already checked by using fflush(stdin)

#include<stdio.h>
int main(){
    char str;
    int n,in;
    scanf("%d",&n);
    for(in=0;in<n;in++){  
        scanf("%c",&str);
        for(in=0;in<n;in++){
            if((str=='b')||(str=='B'))
                printf("Battleship");
            else if((str=='c')||(str=='C'))
                printf("Cruiser");
            else if((str=='d')||(str=='D'))
                printf("Destroyer");
            else
                printf("Fringate"); 
        }
   }
}

When I am providing test case, it is not taking input and getting out of the program.

Give the white space before `%c` to consume the newline character from the input, `scanf(" %c",&str);` And you intended to put `scanf()` inside loop ? else `str` will always same for `n` iteration — Achal, Apr 14 '19 at 04:10
the second loop is not running and it is automatically printing the prevous output — sam, Apr 14 '19 at 04:12
why is that so since i have provided scanf it should scan inside the loop before printing the output — sam, Apr 14 '19 at 04:15
Use differenet variable in second loop, instead of 'in', use some other name — Sabith, Apr 14 '19 at 04:17
why should i give whitespace,please give me the reason for that ,i didnt get the logic to do that — sam, Apr 14 '19 at 04:20
You need `" %c"` because [`scanf()` leaves the newline in the input buffer](https://stackoverflow.com/questions/5240789/scanf-leaves-the-new-line-char-in-buffer). You should be cautious about [Using `fflush(stdin)`](https://stackoverflow.com/questions/2979209/using-fflushstdin); it doesn't work everywhere. You should be testing the return value of `scanf()` every time you call it so you can spot EOF and other problems reliably. — Jonathan Leffler, Apr 14 '19 at 04:56
Also, in English the ship type is "frigate" not "fringate". And don't you have some squares that have no vessel in them? At the moment, you have frigates everywhere you don't have a bigger vessel. — Jonathan Leffler, Apr 14 '19 at 04:58
