I would like to know how to determine whether string is valid file path.
The file path may or may not exist.

scanf("%f", &num[i]); And, the sum of each entered element is computed. sum += num[i]; Once the for loop is completed, the average is calculated and printed on the screen.
The standard form of a quadratic equation is: ax2 + bx + c = 0, where a, b and c are real numbers and a != 0. The term b2; - 4ac is known as the discriminant of a quadratic equation. It tells the nature of the roots.
Similarly, the remainder is evaluated using % (the modulo operator) and stored in remainder . remainder = dividend % divisor; Finally, the quotient and remainder are displayed using printf( ) . printf("Quotient = %d\n", quotient); printf("Remainder = %d", remainder);
You can use the FileInfo constructor. It will throw a ArgumentException if "The file name is empty, contains only white spaces, or contains invalid characters." It can also throw SecurityException or UnauthorizedAccessException, which I think you can ignore if you're only concerned about format.
Another option is to check against Path.GetInvalidPathChars directly. E.g.:
boolean possiblePath = pathString.IndexOfAny(Path.GetInvalidPathChars()) == -1; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
