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.
