C language output integer in another format

Algorithm design ideas

1. Get the hundred digits of the input number 、 ten 、 bits
2. Store the corresponding information according to the size of each number
3. When printing information , We need to pay attention to ： Characters and numbers are printed separately , Otherwise, digital information cannot be displayed

Code

#include <stdio.h>

int main(){
    
    int n, i;
    scanf("%d", &n);
    int b = (n - n % 100) / 100;
    int g = n % 10;
    int s = (n % 100 - g) / 10;
    char a[27];
    for(i=0; i<b; i++){
    
        a[i] = 'B';
    }
    for(i=0; i<s; i++){
    
        a[b + i] = 'S';
    }
    for(i=0; i<g; i++){
    
        a[b + s + i] = i + 1;
    }
    for(i=0; i<b+s; i++){
    
        printf("%c", a[i]);
    }
    for(i=b+s; i<b+s+g; i++){
    
        printf("%d", a[i]);
    }
    return 0;
}
