51. Output will be 80 because ptr_num will be holding the address of variable "number" and since the latest value of "number" is 80, hence 80 will be printed. Option c is correct.
52. Since pointer "ptr" is pointing to variable "num" and in the statement "*ptr = *ptr+15" , the value of location pointed by ptr which is value of variable "num" will be incremented by 15. Hence the value of "num" will become 30 which is same as *ptr.
Hence the output will be 30 30. So option d is correct.
53. This will generate compilation error because input to the function "atoi() " which converts string to integer should have input of type "const char *" however the the input is not constant character pointer in atoi() function and hence compilation error will be generated.
Hence option c is correct.
Please comment for any clarification.
