|if i want cin 12345678910 and cout abcdefghij.
so how can i create the program?.
example : if i key in 8910 so the answer is ghij.
|Can we remove an element in a single linked list without
Lets suppose the link list is like this
1 2 3 4 5 6
We need to remove 4 from this list (without traversing from
beginning) and the final link list shud be 1 2 3 5 6
only thing we know is the pointer to element "4". How can
we remove "4" and link "3" to "5"?

b) somestring.c_str ()
c) &somestring 
d) std::cstring (somestring)
e) (char *) somestring
|Explain "passing by value", "passing by pointer" and
"passing by reference" ?
|If P is the population on the first day of the year, B is
the birth rate, and D is the death rate, the estimated
population at the end of the year is given by the formula:
The population growth rate is given by the formula:
B – D
Write a program that prompts the user to enter the starting
population, birth and death rates, and n, the number of
years. The program should then calculate and print the
estimated population after n years. Your program must have
at least the following functions:
1. growthRate: This function takes its parameters the
birth and death rates, and it returns the population growth
2. estimatedPopulation: This function takes its
parameters the current population, population growth rate,
and n, the number of years. It returns the estimated
population after n years
Your program should not accept a negative birth rate,
negative death rate, or a population less than 2.
