I have to read in from input file and if a word in that file is longer than 7 letters insert "er" after the 3 letter of that word. I started by reading the file into a cstring. I know how to find the length of the words I just cant figure out how to insert "er" into the word.
any ideas?
thanks
ok.. so how are you finding the length.. have any code..
Code:ifIn.getline(szTemp,20,' '); iLeng=strlen(szTemp); if(iLeng==7) { //do something }
Should be if(iLeng > 7) instead of if(iLeng==7) according to your description.
To merge one string at the end of another, use strcat().

of course there are many different ways to do it, but what I suggest is that you make use of these two functions:
strncpy() and strcat()
but if i do it this way i don't know if it will work for every word in the file because if I loop this for every word in the file my "i" will be at a different point in the file.Code:. . if (iLeng>7) { for(int i=0; i<=2; i++) { ifIn>>temp[i]; } strcat(temp,"er"); // I thought about this but i don't know what to do here
so this is where i get confused
What does Your Variable Temp[i] hold?
If length of the word >7 then
word=word+er
to make word=word+7 you can use the strcpy, strcat functions
Actually that won't accomplish his goal. He needs to:Originally posted by ddavidson
If length of the word >7 then
word=word+er
to make word=word+7 you can use the strcpy, strcat functions
The resultant string should be src[0-2]+"er"+src[3-len]insert "er" after the 3 letter of that word
but, how do I code it so it will work for every word in the file that I need it to. because i am clueless
The steps:
Code:1) read a word from the file 2) if word is > 7 a) copy the first 3 characters to a separate buffer b) concatenate "er" to the separate buffer c) concatenate the 4th to the end of the word to the separate buffer 3) do whatever else you need to do with the buffer (display it, etc) 4) repeat step 1 and continue until end of file
Ooops

Here is a hint for you
S3.insert(3, s4, 0, string::npos); will insert "s4" at location 3 in the string s3.
In other words You insert in your case "er" before s3's third letter
The last two arguments specify the start of the word and the number of characters from s4 that should be inserted in in your case:2
So all you need to find is where to insert the "er"
