Answer 1

Need a second variable <j>, for indexing in <symbolsArray>, use of <i> in your code makes the characters from <input> be copied into undesired position.

for (int i = 0, j = 0; i < strlen(input); i++)
{
if (input[i] == '+' || input[i] == '-' || input[i] == '*' || input[i] == '/')
{
symbolsArray[j++] = input[i];
}
else
{
continue;
}
}
