The const keyword specifies that a variable's value is constant and tells the compiler to prevent the programmer from modifying it. In C, constant values default to external linkage, so they can appear only in source files.

Certainly! In C programming, the const keyword is used to declare a variable as a constant. Once a variable is declared as const, its value cannot be changed throughout the program's execution. This provides a way to ensure that certain data remains constant and cannot be accidentally modified. For example: c #include...

Certainly! In C programming, the const keyword is used to declare a variable as a constant. Once a variable is declared as const, its value cannot be changed throughout the program's execution. This provides a way to ensure that certain data remains constant and cannot be accidentally modified.

For example:

c
#include <stdio.h> int main() { const int MAX_VALUE = 100; // MAX_VALUE = 200; // This would result in a compilation error, as MAX_VALUE is a constant printf("The maximum value is: %d\n", MAX_VALUE); return 0; }

In the code above, MAX_VALUE is declared as a constant with a value of 100. Any attempt to modify its value later in the program will result in a compilation error.
