Point out error, if any, in the following program main() { int i=1; switch(i) { case 1: printf("nRadioactive cats have 18 half-lives"); break; case 1*2+4: printf("nBottle for rent -inquire within"); break; } }

Yes, the ans is A) i.e. No Error.In switch case we can place any constant (only integer or character not any floating point number). Here 1*2+4 is an expression and the value of the expression is 6 i.e constant which is applicable in switch case.

Output is: 22for sizeof('a') compiler takes the ASCII value of 'a' and ASCII value is integer so answer is 2for sizeof("a") compiler also count NULL() so total characters are 2 hence answer is 2

Converts an integer value to a null-terminated string using the specified base.If base is 10 and value is negative, the resulting string is preceded with a minus sign (-). With any other base, value is always considered unsigned.
