How do you combine two hex values?

2 Answers. int num1,num2,num3; num1=0x25; num2=0x71; num3=(num1<<8)|(num2); printf(“%x %d”,num3,num3); You need to place 25 (0025) followed by 71 (0071) in a variable, so you have to left shift the first number by 8 bits (0025 to 2500) and combine it with num2.

1. Divide the decimal number by 16. Treat the division as an integer division.
2. Write down the remainder (in hexadecimal).
3. Divide the result again by 16. Treat the division as an integer division.
