When a runtime error occurs, the computer stops the execution of program and displays an error message. Alternatively, you could read words using scanf with the %s conversion: char buffer[256]; while (scanf("%255s", buffer)) printf("%s\n", buffer); This approach, however, imposes an upper limit on the size of a single error example: if (touchValue > 1); { tone(speaker, note); delay(100); } fixed example: if (touchValue > 1)_ { tone(speaker, note); delay(100); } For example, in the code above on the top, Is it possible that the last piece the ant has eaten is the central one?

For example, in the code below, the last line of the song procedure (delay(20000);) will make your project stop and do nothing for 20,000 milliseconds—that’s 20 seconds, a very long time!

These errors are the trickiest to find and fix because the Arduino software doesn’t give you any feedback about what might be causing the problem, like it does with compile and upload errors.

Syntax error occur when syntax of a programming language are not followed in writing the source code. If this happens, your computer will probably crash. Find the errors in following programs. 1. #include "iostream" void main() { const PI=3.14; int r,h; cout>>"Enter values of r and h' cin>>r,h; v=PI*r*r*h; cout<<'volume="< #define p=10000 int The compiler detects these errors at compiling time of source code.

For example, assigning a value to the wrong variable may cause a series of unexpected program errors.

INCORRECT VARIABLE INITIALIZATIONS error example: int C = 10; int D = 1175; int E = 1319; int F = 1397; int G = 15; int A = 17600; int B void main() { int a,b; cin<
