In C, the int
data type typically occupies 2 bytes (16 bits) on systems where it is defined as a short integer. This size allows it to represent a range of values from -32,768 to 32,767 in a signed format. However, the actual size of an int
can vary based on the architecture and compiler, with many modern systems using 4 bytes (32 bits) for int
. It's essential to check the specific implementation or use fixed-width types like int16_t
for consistent behavior across platforms.
In C, the memory consumption for an integer typically depends on the system architecture. On most platforms, a standard int takes up 4 bytes (32 bits) of memory. However, it can vary; for example, on some older or specific architectures, it might be 2 bytes (16 bits) or, in cases with larger data types, it could be 8 bytes (64 bits). The exact size can be determined using the sizeof(int) operator in C.

If ( c - 8 ) is an odd integer, then ( c ) must be an odd integer as well. This is because subtracting an even number (8) from an odd number results in an odd number. Therefore, possible values for ( c ) could be any odd integer such as 1, 3, 5, 7, etc. In general, ( c ) can be expressed as ( c = 2k + 1 ), where ( k ) is an integer.
They are the same. A fraction is one integer divided by another integer. A rational number can be expressed as the quotient of two integers. If you're wondering about the easier method for dividing two fractions, say ( a / b ) / ( c / d ) it would be ( a / b ) * ( d / c ).
It completely depends the datatype that you have assigned for the variables 'a' , 'b' , and 'c'. Check the compiler that you are using for the size of the datatype in bytes. Add them and thus you will get the answer.
A plain integer variable in C under windows is 2 bytes in 16 bit windows, and 4 bytes in 32 bit windows.

It depends on the context. Each database and computer language define an "integer". In the C language an integer is defined by the hardware. It can vary from 2 to 8 bytes or more.
Data-type (short for integer).
Different computer languages use different amounts of memory to store integers. For example, C++ uses a minimum of 4 bytes, Java a min of 8 bytes. A long integer is one which is requires more bytes than the standard amount. When the storage requirement gets to twice the standard amount, the number becomes a double integer.

4 bytes
Usually four bytes.
Not sure what you mean; if you want to measure the "input size" in bytes, that would probably be 8 bytes, since integers typically use 4 bytes.
Because you are using a compiler (TurboC, most likely) which was developed some 25 years ago, for a 16-bit platform.
The number of bytes required to store a number in binary depends on the size of the number and the data type used. For instance, an 8-bit byte can store values from 0 to 255 (or -128 to 127 if signed). Larger numbers require more bytes: a 16-bit integer uses 2 bytes, a 32-bit integer uses 4 bytes, and a 64-bit integer uses 8 bytes. Thus, the number of bytes needed corresponds to the number of bits needed for the binary representation of the number.
