C++ Exercises: Create a new string from a given string where a specified character have been removed except starting and ending position of the given string
C++ Basic Algorithm: Exercise-33 with Solution
Write a C++ program to create a new string from a given string where a specified character is removed except at the beginning and end.
Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
string test(string str1, string c)
{
for (int i = str1.length() - 2; i > 0; i--)
{
if (str1[i] == c[0])
{
str1 = str1.erase(i, 1);
}
}
return str1;
}
int main()
{
cout << test("xxHxix", "x") << endl;
cout << test("abxdddca", "a") << endl;
cout << test("xabjbhtrb", "b") << endl;
return 0;
}
Sample Output:
xHix abxdddca xajhtrb

Previous: Write a C++ program to check a given array (length will be atleast 2) of integers and return true if there are two values 15, 15 next to each other.
Next: Write a C++ program to create a new string of the characters at indexes 0,1, 4,5, 8,9 ... from a given string.

C++ Programming: Tips of the Day
What is the "-->" operator in C/C++?
--> is not an operator. It is in fact two separate operators, -- and >.
The conditional's code decrements x, while returning x's original (not decremented) value, and then compares the original value with 0 using the > operator.
To better understand, the statement could be written as follows:
while( (x--) > 0 )
