This comprehensive course covers the fundamentals and advanced concepts of C programming to build a solid foundation for your programming journey. You’ll learn about essential topics like data types, variables, constants, and C statements, along with deeper explorations of control flow in C, including for loops and conditional statements in C. You’ll also learn about C functions, scope of variables, function arguments, and work with arrays, strings, and pointers in C.

You’ll gain hands-on experience with dynamic memory allocation, stack vs. heap, C standard library, and advanced topics such as binary files, input and output streams, and header files. The course also teaches compiling in C, linking in C, and debugging with tools like GNU debugger (GDB) and gprof for code profiling. By mastering these concepts, you’ll confidently program in C and optimize your code using gcc optimization flags.

# The `break` statement

There is a special statement in C called `break` that allows us to
exit from a loop earlier. It overrides the loop condition at the top (or bottom) of the loop, and "breaks" out of the loop. 


#include <stdio.h>

int main(void) {
  // Check whether 80 is in the first 20 multiples of 5
  int mult = 0;
  for(int i = 1; i <= 20; i++) {
    mult = 5 * i;
    if( mult == 80 ){
      printf("80 is in the first 20 multiples of 5.\n5 x %d = %d\n", i, mult);
      break;
      printf("The loop does not reach this point\n");
    }
  }  
  printf("The loop has ended");
  return 0;
}

As you can see in the code above, even though our loop's ending condition hasn't been fulfilled, the `break` statement does not allow the loop to run to completion. As a result, the `printf` statement on **line 11** isn't executed. Instead, the program jumps directly to **line 14**.

We'll see in the next lesson how a `break` statement can also be used for breaking out of switch statements.

# The `continue` statement

The `continue` statement is not used very often. It causes the next iteration of a loop to begin without executing the code that's still left in the current iteration. It can be thought of as a sort of instruction to "do nothing, just continue".

Learn about the break and continue keywords and their usage in the context of loops.
