Conversão binário - octal

[rodiisilva]

Boa noite, senhores. Gostaria da ajuda de alguém aqui do fórum, pois, o meu compilador( Dev C++). Aponta diversos erros e warnings no meu código.

Abaixo do código fonte segue a lista de erros

#include<stdio.h>
#include<stdlib.h>
#include<stdbool.h>
#include<string.h>
#define TAM 121


int main (void) {
    int a, b, j, i, octal;
    char nb[TAM];
    bool valido;
    printf("Digite um numero binario:\n");
    scanf("%120[^\n]", nb);
    
    j = 0;
    while (nb[j] == ' '); {
          j++;
    }
    for (i = 0; j <= strlen(nb); j++; i++) {
        nb[i] = nb[j];
    }
        j = strlen(nb) - 1;
    while (nb[j] == ' '); {
          j--;
    }
    valido = true;
    for ( i = 0; i < strlen(nb); i++) {
        if ((nb[i] != '0') && (nb[i] != '1')) {
                   printf("Numero binario invalido\n");
                   valido = false;
                   break;
        }
    }
    
    a = strlen(nb) / 3;
    b = strlen(nb) % 3;
    
    
    for (i=0; i<a; i++) {
            j = i * 3 + b;
            octal = (nb[j] - 48) * 4 + (nb[j + 1] - 48) * 2 + (nb[j + 2] - 48);
            printf("%c%c%c ~> %d\n", nb[j], nb[j + 1], nb[j + 2], octal);
            }
            
            printf("\n");
            }
            printf("\n");
            
   
   
                
    system("PAUSE");
    
    return (0);
}
