copied!<p>i have a pretty weird problem. what im doing is im trying to convert a 8-digit binary number in a string to a decimal number (string also) at the end of the code i cout the binary string and the decimal string but when i ran, i only successfully see the binary string but not the decimal string...</p> <p>heres my code:</p> <pre><code>#include <iostream> #include <string> #include <stdlib.h> using namespace std; void bintodec(string bin); int main() { string bin=""; bintodec(bin); return 0; } void bintodec(string bin) { int temp; int temp_a; int temp_b; string dec; cout << "Enter the binary number: "; cin >> bin; temp = 128*(bin[0]-48) + 64*(bin[1]-48) + 32*(bin[2]-48) + 16*(bin[3]-48) + 8*(bin[4]-48) + 4*(bin[5]-48) + 2*(bin[6]-48) + (bin[7]-48); temp_a = temp%10; temp = (temp - temp_a) / 10; temp_b = temp%10; temp = (temp - temp_b) / 10; dec[2]=temp_a+48; dec[1]=temp_b+48; dec[0]=temp+48; dec[3]='\0'; cout << endl << bin << " in decimal is: " << dec << endl; } </code></pre> <p>and here is the running result:</p> <blockquote> <p>Enter the binary number: 10101010</p> <p>10101010 in decimal is:</p> </blockquote> <p>after "is" there should be my decimal number; however theres nothing. i tried to cout dec[0] dec[1] and dec[2] individually and it worked, but when i cout the whole dec, i failed every time...</p> <p>could anyone tell me where my problem is? i think i have something wrong with my code but i could figure it out...</p>
