- 1. Part I (1.5 points) Write a C++ programthat reads a line fromthe keyboard, and that returns the number oflowercase letters inthe line. Your code should containa functionthat determines the totalnumber oflowercase letters inthe line. The functionMUSTbe parameterized (i.e. nonemptyparameter list). Be sure to use proper formattingand appropriate comments inyour code. The followingshows a sample runofthe program. Enter a sentence:Hi, World, HOW are you? The totalnumber oflowercase letters inthe sentence is 11 Part II (1.5 points) Write a C++ programthat determines the largest amongthree numbers ofint type read fromthe keyboard. Your code should containa functionthat determines the largest amongthe three numbers passed to it. Callbyreference MUSTbe used to implement the function. Be sure to use proper formattingand appropriate comments inyour code. The followingshowa sample runofthe program. Enter three numbers separated bya space:17 36 29 The largest number among17, 36, and 29 is 36 Part III (1.5 points) Write a C++ programto convert a temperature fromFahrenheit to Celsius or a temperature fromCelsius to Fahrenheit, dependingonwhether the user enters anF or a C. YouMUSTuse two functions to implement the two conversions inyour code. Also, declare the two prototypes before main() and define the two functions after main(). Be sure to use proper formattingand appropriate comments inyour code. The following shows a sample runofthe program. Enter anF or a C and a number to be converted:F 78.5 Celsius of78.5 degrees inFahrenheit is 25.833
