Q. Write a program to remove all occurrences of a character in a string.

We are provided a string and a character in input and we will remove each occurrence of that character from the string and output the updated string.

String :- In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable.
For Example :-
String = Letsfindcourse
Character = e Output = Ltsfindcours

Logic : We have a string and a character to be removed. Now we have passed these two parameters to function which will remove all occurrences of given character from string. The entire string except the given character will be displayed as output.

Algorithm

START
Step 1 : Input string variable str and character variable c
Step 2 : Find length of the string
Step 3 : For Loop
			int i = j = 0; i < n; i++
				if str[i] != c 
					str[j++] = str[i];
		Loop End
Step 4 : str[j] = '\0';
STOP

    removeChar(str1,'e')
