Extract Bits Out of Variable in C Programming using Bitwise Operators

If someone wants to extract Bits out of a variable, below-mentioned code explains how it can be done.

1. First of all, we need an array of a 1-byte variable to store all the extracted bits.
2. Then we need a mask variable which is used to check whether a bit is ON or OFF.
3. Then we have to shift 1 bit to the left i times to make masked value.
4. The final step is extracting bits using Bitwise AND and Right-Shift Operator.

char bits[7]={0}; char extract_bits(char val) { short mask; int i; for(i=0; i< 7; i++){ mask= 1 << i; bits[i] = (val& mask)>>i; printf("%d\n",bits[i]); }
