change the case of string in c++

1. Change the case of string in python in C++

Write a function that converts a given string to lower case.

Assume, given string contains uppercase alphabets only. But input can contain multiple words.

Sample Input 1 :

ABCDE

Sample Output 1 :

abcde

Sample Input 2 :

ABC DEF

Sample Output 2 :

abc def

C++ Code:

// Update in the given string itself. No need to return or print anything.

void convertStringToLowerCase(char input[]) {
    // Write your code here
int len=0;
  while(input[len]!='\0')
    len++;
   for(int i=0;i<=len;i++)
    {
    	if(input[i] >= 'A' && input[i] <= 'Z')
          input[i]=input[i] + 32; 
    }

}

2.Remove character from string in c++

For a given a string(str) and a character X, write a function to remove all the occurrences of X from the given string.
The input string will remain unchanged if the given character(X) doesn't exist in the input string.
Input Format:
The first line of input contains a string without any leading and trailing spaces.

The second line of input contains a character(X) without any leading and trailing spaces.
Output Format:
The only line of output prints the updated string. 
Note:
You are not required to print anything explicitly. It has already been taken care of.
Constraints:
0 <= N <= 10^6
Where N is the length of the input string.

Time Limit: 1 second
Sample Input 1:
aabccbaa
a
Sample Output 1:
bccb
Sample Input 2:
xxyyzxx
y
Sample Output 2:
xxzxx
C++ Code:
// input - given string
// You need to remove all occurrences of character c that are present in string input.
// Change in the input itself. So no need to return or print anything.

void removeAllOccurrencesOfChar(char input[], char c) {
    // Write your code here
  int len=0,j;
  while(input[len]!=0)
    len++;
for(int i=0;i<len;i++)
{
  if(input[i]!=c)
  {
    input[j]=input[i];
    j++;
  }
}
  input[j]='\0';
}
