十进制八进制二进制之间的转换代码C语言

以下是C语言实现十进制、八进制和二进制之间的转换代码：

从十进制转换为八进制：

void Decimal2Octal(int decimalNumber) {
    int quotient = 0;
    int octalNumber[100];
    int i = 0;

    quotient = decimalNumber;

    while (quotient != 0) {
        octalNumber[i] = quotient % 8;
        quotient = quotient / 8;
        i++;
    }

    printf("Octal number is: ");
    for (int j = i - 1; j >= 0; j--) {
        printf("%d", octalNumber[j]);
    }
}

从十进制转换为二进制：

void Decimal2Binary(int decimalNumber) {
    int quotient = 0;
    int binaryNumber[100];
    int i = 0;

    quotient = decimalNumber;

    while (quotient != 0) {
        binaryNumber[i] = quotient % 2;
        quotient = quotient / 2;
        i++;
    }

    printf("Binary number is: ");
    for (int j = i - 1; j >= 0; j--) {
        printf("%d", binaryNumber[j]);
    }
}

从八进制转换为十进制：

int Octal2Decimal(int octalNumber) {
    int decimalNumber = 0;
    int i = 0;
    int remainder;

    while (octalNumber != 0) {
        remainder = octalNumber % 10;
        octalNumber = octalNumber / 10;
        decimalNumber = decimalNumber + remainder * pow(8, i);
        i++;
    }

    return decimalNumber;
}

从八进制转换为二进制：

void Octal2Binary(int octalNumber) {
    int decimalNumber = Octal2Decimal(octalNumber);
    Decimal2Binary(decimalNumber);
}

从二进制转换为十进制：

int Binary2Decimal(long long binaryNumber) {
    int decimalNumber = 0;
    int i = 0;
    int remainder;

    while (binaryNumber != 0) {
        remainder = binaryNumber % 10;
        binaryNumber = binaryNumber / 10;
        decimalNumber = decimalNumber + remainder * pow(2, i);
        i++;
    }

    return decimalNumber;
}

从二进制转换为八进制：

void Binary2Octal(long long binaryNumber) {
    int decimalNumber = Binary2Decimal(binaryNumber);
    Decimal2Octal(decimalNumber);
}
