C++: Given three strings on separate lines, insert the contents of the second string in the first string right before the third string. Then, output the result

Ex: If the input is:
FuzzyBear

Wuzzy

Be

the output is:
FuzzyWuzzyBear

Note: Using a pre-defined string function, the solution can be just one line of code.

(I tried using strVar. insert(partStr, str2) but was unsuccessful. I don’t know where I’m messing up. Thank you for your help. I’ve been trying to alter this code for a while now)

Fill in the following program so that it will correctly calculate the price of the orange juice the user is buying based on the buy one get one sale.#include //main functionint main() { int cartons; float price, total; //prompt user for input information printf("what is the cost of one container of oj in dollars? \n"); scanf(" [ select ] ["%d", "%c", "%f", "%lf"] ", & price); printf("how many containers are you buying? \n"); scanf(" [ select ] ["%d", "%c", "%f", "%lf"] ", & cartons); if ( [ select ] ["cartons / 2", "cartons % 1", "cartons % 2", "cartons % price", "cartons / price", "cartons / total"] [ select ] ["=", "==", "! =", "< =", "> =", "< "] 0) total = [ select ] ["price * cartons", "cartons * price / 2 + price", "(cartons / 2) * price", "cartons / (2.0 * price)", "(cartons / 2.0) * price + price", "((cartons / 2) * price) + price"] ; else total = ((cartons / 2) * price) + price; printf("the total cost is $%.2f.\n", total); return 0; }
