User-Defined Methods — Question 36
Back to all questionsQuestion 34
Write a function that takes two char arguments and returns 0 if both the arguments are equal. The function returns -1 if the first argument is smaller than the second and 1 if the second argument is smaller than the first.
class KboatCompareChar
{
int compareChar(char c1, char c2) {
int ret;
if(c1 == c2)
ret = 0;
else if(c1 < c2)
ret = -1;
else
ret = 1;
return ret;
}
}Output
Key Concepts Covered
This question tests your understanding of the following concepts from the chapter User-Defined Methods: Question, Takes, Char, Arguments, Returns, Equal. These are fundamental topics in Computer Applications that students are expected to master as part of the ICSE Class 10 curriculum.
A thorough understanding of these concepts will help you answer similar questions confidently in your ICSE examinations. These topics are frequently tested in both objective and subjective sections of Computer Applications papers. We recommend revising the relevant section of your textbook alongside practising these solved examples to build a strong foundation.
