What will
strcmp('Hello', 'hello') return in MATLAB?It will return
false because strcmp is case-sensitive and 'H' is not equal to 'h'.Click to reveal answer
Which MATLAB function compares two strings ignoring case?
✗ Incorrect
strcmpi compares strings ignoring case differences.What does
strcmp('abc', 'ABC') return?✗ Incorrect
strcmp is case-sensitive, so 'abc' and 'ABC' are not equal.Which function compares only the first N characters of two strings?
✗ Incorrect
strncmp compares the first N characters of two strings.If you want to check if two strings are exactly the same including case, which function do you use?
✗ Incorrect
strcmp checks for exact equality including case.What will
strcmp('MATLAB', 'matlab') return?✗ Incorrect
Because
strcmp is case-sensitive, it returns false.Explain how to compare two strings in MATLAB considering case sensitivity and ignoring case.
