Adding more to the information presented above: When a variable is declared as const, it's stored in read-only section of a memory (.rodata segment). That's the reason when you try to modify the value of that variable, you will get an error: assignment of read only variable. Also, where const is placed also changes the meaning of the declaration. For eg. 1) const int a -> It means a is a constant integer 2) int const a -> Same as 1. It means a is a constant integer 3) const int *a -> Here a is a pointer to a constant integer 4) int * const a -> Here a is a constant pointer to a non-constant integer. The value of pointed integer is modifiable, but the pointer is not modifiable. 5) int const * a const -> Here a is a constant pointer to a const integer that means the value of the pointed integer and pointer both are not modifiable. const qualifier always applies to what is present to it's immediate left. If nothing is on the left, then it applies to whatever is on the right. The whole point of a const qualifier is to make sure you don't accidentally change value of the variable which is supposed to be constant. Though, value of constant integer can be changed through the use of pointers. For eg. const int a = 10; // Here a is a const integer which will not be modifiable int *myPtr = &a; // Pointing to the constant variable *myPtr = 20; // Changing the value of constant variable Now if you print a, you will see value to be 20. The reason why this happens is because the pointer that is pointing to the const variable is a non-constant pointer. If you want to make sure not even a pointer should be able to change the value of a const variable then you should make the pointer a const too. eg. int *const myPtr = &a; This way your const stays safe.

00:00 The video discusses constants in the C programming language. 02:18 Constants in C programming can have fixed values that are not changed throughout the program. 04:53 Integers can be expressed in three forms: decimal, octal, and hexadecimal. 07:47 Numeric constants can be represented as integer constants or real constants. 10:29 Character constants can store single characters enclosed in single quotes. 13:06 Explanation of format specifiers and character constants in C 15:44 Constants in the program can be declared using the 'const' keyword 18:03 Constants can be declared using the 'const' keyword thanks is advance 😜😜

[@olufemiomonikeolusegun8337]

Thanks for this wonderful tutorial Ma'am. Please I have this question to ask about the examples you gave under the HEXADECIMAL CONSTANT. You said 0X7G is invalid because the last character i.e, G is out of range of characters used in HEXADECIMAL (A-F) while 0x7F is correct. Please what happens to the character "x" which is also not in the range of A-F? Please I'll be very glad if you can make available pdf notes on this training. More power to your elbow. I'm enjoying your service to humanity. Bunch of thanks.
