Well, I'm starting my C studies and I was left with the following question, how are the bits of the primitive types filled in, for example, the int type, for example, has 4 bytes, that is 32 bits, which fits up to 4294967296. But if for example , I use a value that takes only 1 byte, how do the other bits stay?

    #include <stdio.h>

    int main(void) {

        int x = 5; // 101 how the rest of the bits are filled
                   // which was not used?
         return 0;
    }

All leading bits will be set to 0, otherwise the value wouldn't be 5. A bit, in today computers, has only two states so if it's not 0 then it's 1 which would cause the value stored to be different. So assuming 32 bits you have that

5 == 0b00000000 00000000 00000000 00000101
5 == 0x00000005

Primitive data type, In computer science, primitive data type is either of the following: a basic type is a data type In particular, the C standard mentions that "a 'plain' int object has the natural size suggested by the architecture of the execution environment". This means that int is likely to be 32 bits long on a 32-bit architecture. Basic primitive� Well, I'm starting my C studies and I was left with the following question, how are the bits of the primitive types filled in, for example, the int type, for example, has 4 bytes, that is 32 bits, which fits up to 4294967296.


The remaining bits are stored with 0.

int a = 356;

Now let us convert it to binary.

 1     0    1     1     0   0   1   0   0

Now you get 9 bit number. Since int allocates 32 bits, fill the remaining 23 bits with 0.

So the value stored in memory is

         00000000 00000000 00000001 01100100

C data types, All leading bits will be set to 0 , otherwise the value wouldn't be 5 . A bit, in today computers, has only two states so if it's not 0 then it's 1 which� In C, each variable has a specific data type, where a data type tells us the size, range and the type of a value that can be stored in a variable. In C, there are about seven primitive data types . These data types are : short, int, long, char, float, double and few of their variants.


The type you have picked determines how large the integer is, not the value you store inside the variable.

If we assume that int is 32 bits on your system, then the value 5 will be expressed as a 32 bit number. Which is 0000000000000000000000000101 binary or 0x00000005 hex. If the other bits had any other values, it would no longer be the number 5, 32 bits large.

Bits of the primitive type in C, The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted. The types in C can be classified as follows� [citation needed] In particular, the C standard mentions that "a 'plain' int object has the natural size suggested by the architecture of the execution environment". This means that int is likely to be 32 bits long on a 32-bit architecture. Basic primitive types are almost always value types.


C - Data Types, Primitive Types in C Language. Feb 28 signed char. The 8-bit signed char data type can hold integer values in the range of -128 to 127. A size modifier specifies the width in bits of the integer representation used. The language supports short, long, and long long modifiers. A short type must be at least 16 bits wide. A long type must be at least 32 bits wide. A long long type must be at least 64 bits wide. The standard specifies a size relationship between the integral types:


Primitive Types in C Language, Such types in C++ however are not always implemented in the same way (an int might be 16, 32 or 64 bits for example) so CNI provides a special C++ type for� A notable exception is Windows, where wchar_t is 16 bits and holds UTF-16 code units) It has the same size, signedness, and alignment as one of the integer types, but is a distinct type. char16_t - type for UTF-16 character representation, required to be large enough to represent any UTF-16 code unit (16 bits).


Primitive types, Summer 2010. 15-110 (Reid-Miller). 4. Common Primitive Types. Type Type. Storage. Range of Values byte. 8 bits -128 to 127 short. 16 bits -32,768 to 32,727 int int c; double z; c = a / b; 6 c = a % b; 4 z = x / y; 6.66666667 c = b % a; 6. Thus, all c compilers provide support for these data types. The following primitive data types in c are available: Integer Data Type, int. Integer data type is used to declare a variable that can store numbers without a decimal. The keyword used to declare a variable of integer type is “int”.
