LANGUAGE: C++ CHALLENGE: A variable c of type char has been declared. Write the necessary code to read in the next character from standard input and store it in c, regardless of whether is a whitespace character.

LANGUAGE: C++ CHALLENGE: Assume that a , b and c are char variables has been declared . Write some code that reads in the first character of the next line into a, the first character of the line after that into b and the first character of the line after that into c . Assume…

LANGUAGE: C++ CHALLENGE: Given the availability of an ofstream object named output, and a string variable name tweet, write the other statements necessary to open a file named mytweet”, display the prompt tweet: and then read an entire line into tweet and then write it out to the file mytweet. (Do not define a main…

LANGUAGE: C++ CHALLENGE: In molecular biology the “alphabet” of genes consists of four chemicals (called nucleotides) represented by the letters A C G T. A triad is a sequence of three nucleotides (for example AGA) and specifies an amino acid, a building block for proteins. A gene consists of a very, very long sequence of…

LANGUAGE: C++ CHALLENGE: A U.S. social security number consists of a string of 9 digits, such as “444422333”. Assume that input consists of a sequence of 9-digit social security numbers with no intervening spaces or separators of any kind: 111223333444422333123456789987654321… Assume that a char array named ssn suitable for storing a social security number as…

LANGUAGE: C++ CHALLENGE: A U.S. social security number consists of a string of 9 digits, such as “444422333”. Declare a char array named ssn suitable for storing a social security number as a C-string, and write a statement that reads in the next 9 characters of standard input into this array. (Assume that the input…

LANGUAGE: C++ CHALLENGE: Declare a char array named line suitable for storing C-strings as large as 50 characters, and write a statement that reads in the next line of standard input into this array. (Assume no line of input is 50 or more characters.)

LANGUAGE: C++ CHALLENGE: Given the char * variables name1 , name2, and name3, write a fragment of code that assigns the largest value to the variable max (assume all three have already been declared and have been assigned values ).

LANGUAGE: C++ CHALLENGE: Given the string variables name1 and name2, write a fragment of code that assigns the larger of the two to the variable first (assume all three are already declared and name1 and name2 assigned values ).

LANGUAGE: C++ CHALLENGE: Write an expression that evaluates to true if and only if the C-string s does not equal “end”.

LANGUAGE: C++ CHALLENGE: Write an expression that evaluates to true if the value of C-string lastName is greater than the C-string “Dexter”.

LANGUAGE: C++ CHALLENGE: Write an expression that evaluates to true if the value of the C-string s1 is greater than the value of C-string s2.
