The while loop condition states that the loop repeats as long as the value of character in element A isn't equal to the null character, which the compiler automatically appends to the end of the string literal here. The putchar function sends a single character from the string to standard output. Variable A is incremented, which keeps the loop marching through the string. Run to see the output. And there's the output. The C language can be delightfully cryptic, and this code can show you how that works. Because the putchar function also returns the character it sends to standard output, I can set the function into the while loops condition, and I can delete the statement here. The test is the same and the output is unchanged, and you are a handsome program, but you could use more improvement. The null character test…
