Algorithm to find ones complement of a binary number
- To find the ones complement of a number, we will toggle the bits of the number. Change all 1's to 0's and all 0's to 1's.
For Example :
Binary Number = 00101011
Ones Complement = 11010100
C program to find ones complement of a number
#include <stdio.h> #include <string.h> int main() { char binaryNumber[100], onesComplement[100]; int counter, error=0, digitCount; printf("Enter a Binary Number\n"); scanf("%s", binaryNumber); digitCount = strlen(binaryNumber); for(counter=0; counter < digitCount; counter++) { if(binaryNumber[counter]=='1') { onesComplement[counter] = '0'; } else if(binaryNumber[counter]=='0') { onesComplement[counter] = '1'; } else { printf("Error :( "); return 1; } } onesComplement[digitCount] = '\0'; printf("Ones Complement : %s", onesComplement); return 0; }
Output
Enter a Binary Number 11110010101 Ones Complement : 00001101010
Enter a Binary Number 10001111 Ones Complement : 01110000
