Here, we will find out the unicode code point at a given index using a C++ program.
Input:
arr = "geEKs"
Output:
The Unicode Code Point At 0 is = 71. The Unicode Code Point At 1 is = 101. The Unicode Code Point At 2 is = 69. The Unicode Code Point At 3 is = 107. The Unicode Code Point At 4 is = 83.
Approach:
If the array/string value is increased then it is not feasible to declare an individual variable for the index. If the string size is decreased then the fixed variables can give Out of Bound Error. To handle these situations we will use a for loop to traverse the given string and print the corresponding code point.
Example:
C++
// C++ program to demonstrate // Unicode Code point // at a given index #include <iostream> using namespace std;
// Driver code int main()
{ // define input array/string
char arr[] = "GeEkS" ;
int code;
// print arr
cout << " Input String = " << arr;
// execute a loop to traverse the arr elements
for ( int i = 0; arr[i] != '\0' ; i++) {
code = arr[i];
// display unicode code point at i-th index
cout << "\n The Unicode Code Point At " <<i<< " is = " << code;
}
return 0;
} |
Output
Input String = GeEkS The Unicode Code Point At 0 is 71 The Unicode Code Point At 1 is 101 The Unicode Code Point At 2 is 69 The Unicode Code Point At 3 is 107 The Unicode Code Point At 4 is 83
Time Complexity: O(n), where n is the array size.
Space Complexity: O(1),
