Assume 4 bytes are used to store int and float, 8 for long, double, and long double. a int X; X = 'F' +10; b. float x; X = sizeof(char) + (float) sizeof(1.0L); c int C = 3; X = 'A' + 'E'-5*C + 'C'; 6. (10 pts) Suppose the variables cand offset are defined by the following statements: charc = ''; int offset = 'e'-'E'; Write C commands that turn into an upper case 'F' using the value in offset and then print the character represented by c
