Please help me answer this question

What is the outcome of each of the following assignment statements or if-condition? For an assignment statement, state the value of the variable being assigned after the execution of the statement. You must explain to get the full credit. Assume the following variable declaration: signed char byte = -50; short ADC_input = 500; unsigned int n; Hint: If you are not sure about an outcome, you can write a program to find out (using AVR studio). [3] byte = ADC_input; [3] n = (unsigned int) byte; [3] n = (int) byte; [3] n = ADC_input + (signed char) byte; [3] n = ADC_input + (unsigned char) byte;

Explanation / Answer

a) byte is a char type so it will store only 8 bit .

and assigning ADC_input to it is a 16 bit variable to

8 bit.

so the first 8 bit will be lost

now the last 8 bit of ADC_input will be byte.

that is -12

b) now the byte is easily be converted to int without loosing

its value so here n=-12

c) similerly here also n=-12

d)

now the 16 bit ADC_input will be added with byte

so answer is 488

e)now because unsign char answer will be 744
