Thread: how to obtain first character of every other word

Hi, Need help with the program
No strings or arrays used in this program, only char.
In a sentence how do I check to see that word should be seperated by a single blank.
How do I capitalize the first charcter of every other word. If the sequence starts with a vowel then the first character of the first word should be capitalised otherwise the second word should be capitalised.
Would appreciate anyones help
Thanks!~

I agree, but it is suppose to read each character by character and also read in spaces using cin.get(). can you tell me how to check for the first char?
Thanks

Then it can't be done. You need to put the line in an array and go through it reading spaces until you read two and then the next character gets changed to upper case.

look for an ascii table somewhere then use it to compare the char.

char test;
cin >> test;

if( test == ' ' ) //check that its a space
{
//do this bit....
}


when you know the ascii values it is easy to chek that its upper or lower case, and so on. But you are severly limited if you cant use arrays or strings, are you sure about that?

why isn't my program working??

char ch;
int countspace=0;
cout << "Please enter a line of text, ";
cout << "followed by a return: ";
cout << endl;
cin.get(ch);
while (ch == '\n')
{
if (ch == ' ')
countspace++;
if(countspace > 0 && ch != ' ')

ch= toupper(ch);
cout <<ch;
countspace = 0;
}

Problem:

change this:


File A:
an apple a day
keeps the doctor away

into this:

File B:
An apple A day
keeps The doctor Away

without using strings or arrays.


Here's my first pass at an algorhythm to solve this problem. I'm sure there are going to be plenty of pitfalls for you to overcome, but it demonstrates one way to approach the problem, and a place to start from if you elect to go this way.


declare stream to read from file A and write to file B

declare char dummy to hold input and analyze it

declare counter to keep track of spaces in each line, initialize to 0

read first char into dummy

Outer loop:
while dummy != EOF
assign 0 to counter

outer IF:
if dummy is vowel
change dummy to upper case
write dummy to B
read next char into dummy

Inner Loop:
as long as dummy not newline or EOF

inner IF:
if counter equals 2
change dummy to upper case
write dummy to B
assign 0 to counter
read in next char to dummy
end inner IF

inner else if counter != 2 and dummy is space
increment counter
write dummy to B
read in next char to dummy
end else if

inner else if counter != 2 and dummy is not space
write dummy to B
read in next char to dummy
end else if

end inner loop
end outer IF

outer else if dummy != vowel and dummy != newline char and dummy != EOF
bool initialSpace = false

inner loop
while dummy is not newline or EOF

inner if
if initialSpace is false and counter is 0 and dummy is not space
write dummy to B
read in next char to dummy
end inner if

inner else if initialSpace is false and counter is 0 and dummy is space
assign 1 to counter
write dummy to B
read in next char to dummy
end inner else if

inner else if initialSpace is false and counter is 1 and dummy is not space
change dummy to upper case
write dummy to B
change counter to 0
read in next char to dummy
end inner else if

inner esle if initialSpace is true and counter is 2
change dummy to upper case
write dummy to B
change counter to 0
read in next char to dummy
end inner esle if

inner else if initialSpace is true and counter != 2 and dummy is space
increment counter by 1
write dummy to B
read in next char to dummy
end inner else if

inner else if initialSpace is true and counter != 2 and dummy is not space
write dummy to B
read in next char to dummy
end inner else if

end inner loop
end outer else if

outer else if dummy is newline char
write dummy to B
read next char to dummy
end outer else if.

end outer loop


Good luck
