8.11 LAB: Count characters - functions Write a program whose input is a character and a string, and whose output indicates the n

Shkiper50 [21]

Answer:

#include<iostream>

using namespace std;

int CountCharacters(char userChar, const string inputstr){

int k = 0;

int iter = 0;

for (iter = 0; iter < inputstr.size(); iter++){

if (inputstr[iter] == userChar){

++k; }}

return k;}

int main(){

string str;

char userChar[1];

cout<<"Char: "; cin>>userChar;

cin.ignore();

cout<<"String: "; getline(cin, str);

cout<<CountCharacters(userChar[0],str);

return 0;}

Explanation:

Written in C++:

The function is defined here:

int CountCharacters(char userChar, const string inputstr){

This initializes a count variable k to 0

int k = 0;

This initializes an iterating variable iter to 0

int iter = 0;

This iterates through the characters of the string being passed to the function

for (iter = 0; iter < inputstr.size(); iter++){

This checks for matching characters

if (inputstr[iter] == userChar){

If found, k is incremented by 1

++k; }}

This returns the total count

return k;}

The main begins here

int main(){

This declares a string variable

string str;

This declares a character variable

char userChar[1];

This gets input for the character variable

cout<<"Char: "; cin>>userChar;

This lets the user get another input

cin.ignore();

This gets input for the string variable

cout<<"String: "; getline(cin, str);

This calls the function and return the count of character in the string

cout<<CountCharacters(userChar[0],str);

Lasso: R example

To run Lasso Regression you can re-use the glmnet() function, but with the alpha parameter set to 1.

# Perform 10-fold cross-validation to select lambda --------------------------- lambdas_to_try <- 10^seq(-3, 5, length.out = 100) # Setting alpha = 1 implements lasso regression lasso_cv <- cv.glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = TRUE, nfolds = 10) # Plot cross-validation results plot(lasso_cv)

Best cross-validated lambda lambda_cv <- lasso_cv$lambda.min # Fit final model, get its sum of squared residuals and multiple R-squared model_cv <- glmnet(X, y, alpha = 1, lambda = lambda_cv, standardize = TRUE) y_hat_cv <- predict(model_cv, X) ssr_cv <- t(y - y_hat_cv) %*% (y - y_hat_cv) rsq_lasso_cv <- cor(y, y_hat_cv)^2 # See how increasing lambda shrinks the coefficients -------------------------- # Each line shows coefficients for one variables, for different lambdas. # The higher the lambda, the more the coefficients are shrinked towards zero. res <- glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = FALSE) plot(res, xvar = "lambda") legend("bottomright", lwd = 1, col = 1:6, legend = colnames(X), cex = .7)
