QUESTION 2

The code below is supposed to take an arbitrary number of integers from the input and calculate the mean of the numbers. You are supposed to complete the functions add_array() and get_mean() without changing the code given in the main function.

The main() function is as follows.

int main(){

int n=1;

while(scanf("%d",&d)) {

n++;

}

Output Format: The output is the mean. The output is rounded to two decimal places. The output code is given in the main function snippet.

QUESTION 3

2. void cyclicShift(char* substr, int len) - Shift substring cyclically towards the right by 2 places. Eg: "abcde" ? "deabc".

3. void swapCase(char* substr, int len) - Swap the cases of all alphabets in substr. Eg: "Ab2" ? "aB2".

Input Format:

The first line is the input string str (newline is not part of the string). The second line specifies the number of queries q. The next q lines are triplets (type, start, end), representing the transformations you have to carry out in order.
