toupper is used to change the case of given character to upper case
There are no commands in C-programming, you should use function sqrt from math.h
Sizeof is an example.
No.
with toupper and tolower, from ctype.h
1. identifier 2. short for function
it is sqrt in header math.h
In C programming, a precondition is a condition that must be true before a function is called, while a postcondition is a condition that is guaranteed to be true after the function has been executed.
Sequential style, or function-oriented. Which is opposed to object-oriented, as in C++.
its quite simple using printf function
printf, fgets, strlen, malloc etc
In C-programming: int main (void) { return 0; }
I believe characters have a toUpper() function. For example: char x = 'a'; printf("%c\n", x.toUpper()); // This should print "A" You could also add or subtract using ascii values - remember, a char is pretty much an integer, just displayed differently. For example: printf("Character %c = decimal %d\n", x, x); will display your character and its ascii integer equivalent.
