- (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.Write a C++ function to find nth term of sequence given below, n is passed as argument to the function and function prints the nth term in output. Sequence: 1,4,9,16,25,........n2- Highlight Draw 1 #include \\ function 3 int main () { int a = 3; 6. float b = 4.5; %3D int c = 5.25; %3D 8. float sum; 9. 10 sum = a + b + c 11 12 printf("The sum of a, b, and c is 8f.", sum); 13 return 0; 14 A function written in C++ is shown in the box above.
