What type of a statement is this if a B?

A statement of the form “If A, then B” asserts that if A is true, then B must be true also. If the statement “If A, then B” is true, you can regard it as a promise that whenever the A is true, then B is true also.

What is the value of following expression when A and B are variables of type int with values 1&2 respectively a B == A ++?

String message; This statement is a declaration, because it declares that the variable named message has the type String . Each variable has a type that determines what kind of values it can store. For example, the int type can store integers, and the char type can store characters.

Is int the same as long int?

The difference is that an int is 16 bits or and a long is a 32 bit or and just to cover all of my bases a long long is a 64 bit integer or , which means that you can use a number from (-)65,536 to 65,536 in size with an int, and you can use a number from -4,294,967,296 to 4,294,967,296 in size with a long, and a long …

How do you use long long int?

long int

1. A long int typically uses twice as many bits as a regular int, allowing it to hold much larger numbers.
2. printf and scanf replace \%d or \%i with \%ld or \%li to indicate the use of a long int.
3. long int may also be specified as just long.

Which of the declaration is correct int length char int int long float double?

int long; here long is a keyword cannot be used a variable name. float double; here double is a keyword cannot be used a variable name. So, the answer is int length;(Option A).

What is a long int?

A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 bits. This doesn’t necessarily mean that a long long is wider than a long . Many platforms / ABIs use the LP64 model – where long (and pointers) are 64 bits wide.

Can long and int be compared?

@WeishiZeng: Yes, absolutely. Both operands in a + 1 are int – so that addition happens in int arithmetic, then the conversion to long , then the comparison.

Is long int 64 bit?

int is 32 bits in size. long , ptr , and off_t are all 64 bits (8 bytes) in size.

What is long long int c?

According to C99 standard, long long is an integer type which is at least 64-bit wide. There are two integer 64-bit types specified: long long int and unsigned long long int. So, yes, this is the biggest integer type specified by C language standard (C99 version). There is also long double type specified by C99.
