Pointer comparison operators. Comparison operators can be used to compare two pointers (or pointers-to-members, for operator and operator! = only), or a pointer to member (since C14) and a null pointer constant, or two null pointer constants (but only as long as at least one of them is std::nullptrt: comparison of NULL and NULL follows arithmetic comparison rules) (until C14). To solve this problem in C, you can create an integer array having 100 elements. An array is a collection of data that holds fixed number of values of same type. For example: int age100; Here, the age array can hold maximum of 100 elements of integer type. The size and type of arrays cannot be changed after its declaration. The result of a logical expression cannot be assigned to an int variable, but it can be assigned to a bool variable. Answer Selected Answer: False Correct Answer: False Question 17 1 out of 1 points Consider the following statements. Int score; string grade. Feb 20, 2016 I don't mean any disrespect User-. But basically what you did is shifted 2 (00000010) 5 times i.e. (01000000) which is 64 in decimal, and what he wanna do is find the value of 2^n (2^5) in this case. The use of a block tells the compiler that the else statement should attach to the if statement before the block. Without the block, the else statement would attach to the nearest unmatched if statement, which would be the inner if statement. Using logical operators with if statements. You can also have if statements check multiple conditions together by using the logical operators (covered.
morning everyone.
i hope someone out there could really help me.
im trying to store large numbers. as i need to complete my work under Dev-c++ environment but im not familiar with it as i just started using it recently.
the following is my initial coding for my work.
after i compile using Dev-C++, it shows this error description:
invalid conversion from 'char' to 'const char*'
initializing argument 1 of 'int atoi(const char*)'
i've tried all ways to modify my coding but i just cant get it.
really would be happy if someone could help me.
hope to receives some replies as soon as possible.thank you.
My guess is the problem is in stack2.cpp. But since you did not post it there is no way to tell. Also please post the exact error message including file and line number

Microsoft C also permits the declaration of sized integer variables, which are integral types of size 8-, 16-, 32- or 64-bits. For more information on sized integers in C, see Sized Integer Types.

UCHAR_MAX | Maximum value for a variable of type unsigned char. | 255 (0xff) |
CHAR_MIN | Minimum value for a variable of type char. | -128; 0 if /J option used |
CHAR_MAX | Maximum value for a variable of type char. | 127; 255 if /J option used |

If a value exceeds the largest integer representation, the Microsoft compiler generates an error.
