Hi All I am trying multipy function.After compliering, the a value is 0x78H, b is 0x02H. So, if I want addition function d=a+b(0x78+0x02H)to next line, how define variable a,b to get through with my request. void main(void) { while(1){ char a,b,c,d; a=0x9e; b=0x04; c=a*b; //a=0x78 b=0x02 d=a+b; //this line is 0x9e+0x04 } }
After compliering, the a value is 0x78H, b is 0x02H. How did you determine these numbers? Are you sure you weren't looking at the CPU registers A and B, rather than your variables a and b? You may want to re-think using 'a', 'b' and 'c' as variable names if you're compiling in the default case-insensitive mode.
