Question

Implementing Numerical Integration Using Function Pointers
The problem is to write a function "integrate" with prototype:
//FUNC represents functions of one variable that take a double as input and returns a double
typedef double (*FUNC)(double);
double integrate(FUNC f, double a, double b);
so that when it is passed a function f and bounds a and b, the call:
integrate(f, a,b) will return the value of the definite integral of f evaluated between a and b.
test integrate on the following three functions:
1. double line(double x){
return x;
{
2. double square(double x}{
return x*x;
{
3. double cube(double x){
return x*x*x;
And the following main function:
int main(){
cout<< "The integral of f(x)=x between 1 and 5 is: "<<integrate(line, 1, 5)<<endl;
cout<< "The integral of f(x)=x^2 between 1 and 5 is: "<<integrate(square, 1, 5)<<endl;
cout<< "The integral of f(x)=x^3 between 1 and 5 is: "<<integrate(cube, 1, 5)<<endl;
}
How does integrate work?
Inside a loop we sum up the area of rectangles with a small base (say .0001) and height f(x) for
each x between a and b in increments of .0001.
When the loop terminates, we return the value of the sum.
The purpose if this assignment is to see (and implement) a very simple application of function
pointers.

Write in C++ When you're processing data, it’s useful to break up a text string into pieces using a delimiter. Write a function split() that takes a string, splits it at every occurrence of a delimiter, and then populates an array of strings with the split pieces, up to the provided maximum number of pieces. Function specifications: Name: split() Parameters (Your function should accept these parameters IN THIS ORDER): input_string string: The text string containing data separated by a delimiter separator char: The delimiter marking the location where the string should be split up arr string array: The array that will be used to store the input text string's individual string pieces arr_size int: The number of elements that can be stored in the array Return Value: int: The number of pieces the input text string was split into Note: No input will have delimiters in the beginning or the end of the string.

I need a simple c++ code
In Phython Language: The DNA of a living organism consists of a string of 4 different bases represented with letters A, T, G, C. The DNA has a double helix structure which means these bases are paired in the string. An A base is always paired with a T base molecule and a C base is always paired with G molecule. Write a function matchingPair that accepts a single strand of the DNA structure as a string parameter and produces the pairing strand as a result and returns it. Strings can be considered as list of characters. Therefore the subscript notation that we use for lists is acceptable for strings as well. For example to reach to the 4th character of a string variable mystring, you may use the notation mystring[3]. Write another function search that accepts a long and a short DNA strand as parameters. The function should return the index positions of the occurrences of the short strand in the long strand as a list. Test your functions by accepting a long strand of DNA to find the…
