Write the python3 code for the given problem.... Please write C++ code also.... It's urgent!!!!!!!!!!

Write a python program that uses nested loops to display a pattern like the examples below. It must not use any formatting operators (e.g., string concatenation) to print the strings to the terminal. Example pyramid ./ ...// ...../// .......//// ........./////

The output is actually missing one hi -2 at the end before mark - 1 Code in C Program (Not C++ or Python)

/* Write a high-security program in C that takes two numbers from STDIN and prints out their sum. Input: 35 100 Output: 135 */

Write a program in C that takes in an integer in the range 11-100 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. End with a newline.

Write a C program that will take a string and another number as input. Shift all the characters of the string by that numerical value. The string will consist of only small letters. Look at the explanation for more clarification. Sample Input: smiley 5 Sample Output: xrnqjd Explanation: Here, the first character was s and it has been shifted by 5 units, that is, s+5 = x, thus we got the character ‘x’ in the output. Similarly all the character by shifting the characters by 5 units. Take a closer look at the last character. The character was ‘y’ but after shifting it by 5 units we got ‘d’. That is because we traversed the letters in a circular fashion. After ‘y’ comes ‘z’ then ‘a’ then ‘b’ then ‘c’ and then finally ‘d’. Thus, ‘y’+5 will be ‘d’ in our program. Be careful about this case.

Find out about Java’s switch-case statement. What is its -purpose? How is it used? Write an example. (This is also a control flow -statement, so you will find information in similar locations as for the do-while loop.)
