C 語言實(shí)例 - 八進(jìn)制與二進(jìn)制相互轉(zhuǎn)換
C 語言實(shí)例八進(jìn)制與二進(jìn)制相互轉(zhuǎn)換。
實(shí)例 - 二進(jìn)制轉(zhuǎn)換為八進(jìn)制
#include <stdio.h>
#include <math.h>
int convertBinarytoOctal(long long binaryNumber);
int main()
{
long long binaryNumber;
printf("輸入一個(gè)二進(jìn)制數(shù): ");
scanf("%lld", &binaryNumber);
printf("二進(jìn)制數(shù) %lld 轉(zhuǎn)換為八進(jìn)制為 %d", binaryNumber, convertBinarytoOctal(binaryNumber));
return 0;
}
int convertBinarytoOctal(long long binaryNumber)
{
int octalNumber = 0, decimalNumber = 0, i = 0;
while(binaryNumber != 0)
{
decimalNumber += (binaryNumber%10) * pow(2,i);
++i;
binaryNumber/=10;
}
i = 1;
while (decimalNumber != 0)
{
octalNumber += (decimalNumber % 8) * i;
decimalNumber /= 8;
i *= 10;
}
return octalNumber;
}
輸出結(jié)果為：
輸入一個(gè)二進(jìn)制數(shù): 101001 二進(jìn)制數(shù) 101001 轉(zhuǎn)換為八進(jìn)制為 51
