How to call functions inside a function in Python?

C++ help in setting up a function?

• how do i write this in c++ just need help to figure it out Write a C++ program that uses, in addition to the 'main()' function, three additional functions called: DemonstrateAForAndWhileLoop() DemonstrateForLoop() DemonstrateWhileLoop() The first of these three functions does not return any value to the calling function. The last two of these three functions both return an 'int' value to the calling function. Declare the function prototypes for these three functions above the 'main()' function. --------------------- In the 'main()' function just call the first of the above three functions, and then include the standard return statement for the 'main()' function. --------------------- In the 'DemonstrateAForAndWhileLoop()' function, declare a variable to store how many positive numbers the user has entered. Initialize this variable to 0. Then increment this variable by the return value that you get by calling the 'DemonstrateForLoop()' function. Then increment this variable by the return value that you get by calling the 'DemonstrateWhileLoop()' function. Then print out how many positive numbers the user has entered In the 'DemonstrateForLoop()' function declare a variable to store the number of positive integers that the user has entered in this function so far. Declare any other variables that you need in order to store an integer that the user enters, and a sum of the positive integers that the user has entered. Define a 'for' loop that is set up to execute 5 times. Declare the index variable for the 'for' loop above the 'for' loop. Initialize all of the variables that you have declared that you need to initialize to their correct initial values in the "initialization" part of the 'for' statement. On each iteration ask the user to enter a positive integer, and read in and store what the user enters. If the user has entered a non-positive integer, then use a 'continue' statement to immediately go on to the next iteration of the 'for' loop. Otherwise, increment the variable that stores the number of positive integers that the user has entered in this function so far, and then, if the sum of the positive integers that the user has entered so far is greater than 100, use a 'break' statement to exit from the 'for' loop. After the 'for' loop, print out the sum of the positive integers that the user entered, and then return the the number of positive integers that the user entered in this function as the "return value" from the function. In the 'DemonstrateWhileLoop()' function, declare a variable to count how many positive numbers the user has entered so far, and initialize this variable to 0. Declare and initialize (if necessary) any other variables that you need in order to store an integer that the user enters, and a sum of the positive integers that the user has entered. Then define a 'while' loop that only executes if the sum of the positive integers that the user has entered so far (in the 'DemonstrateWhileLoop()' function) is less than or equal to 100. On each 'while' loop iteration, ask the user to enter a positive integer, and read in and store what the user enters. If the user has entered a non-positive integer, then use a 'continue' statement to immediately go on to the next iteration of the 'while' loop. Otherwise, increment the sum of the positive integers that the user has entered, and increment the variable counting how many positive numbers the user has entered so far. After the 'while' loop, print out the sum of the positive integers that the user entered, and then return the the number of positive integers that the user entered in this function as the "return value" from the function. --------------------- just need help setting it up thanks

• Answer:

  int DemonstrateForLoop(){ int count=0, sum=0; for(int i=0;i<5;i++) { int N; cin>>N; if(N<0) continue; count++; sum+=N; if(sum>100) break; } cout<<sum<<endl; return count; } int DemonstrateWhileLoop(){ int count=0, sum=0; while(1) { int N; cin>>N; if(N<0) continue; count++; sum+=N; if(sum>100) break; } cout<<sum<<endl; return count; } DemonstrateAForAndWhileLoop(){ int count=0; if(DemonstrateForLoop())count++; if(DenonstrateWhileLoop())count++; cout<<count<<endl; }
