Ok new Interger query!
-
Ok if I have a number (stored in a regular integer) and say that number is 51.... Is there a function to search the Integer and return how many numbers there are in the Integer? e.g. 51 has a 5 and a 1 in it so it should return 2. I tried -> sprintf(IntLength, "%d", Prime); but I get compilation errors :-( does anyone have any ideas? Thanks of course in advance :-)

Here sprintf() will convert your prime integer to the string representation. so it will not give you your answer that how many numbers in integer. And Regarding to your error , check the type of variable IntLength used in sprintf() function.

Whats the error? any way you can use the following function for it
int n = 12345678; int nCount = 1; while( n ) { n = n/10; if( n > 0 ) { nCount++; } }nave [OpenedFileFinder]

int iCount = 0; int iurNumber= any number; while(iurNumber !=0) { iurNumber /=10; iCount++; } iCount will contain number of element integer have

technically you are not 100% correct. the return value of sprintf() is the number of characters stored in buffer so adapting the answer to the previous question Michael asked given by Naveen.R here[^] you could end up with
int IntLength; int n = 123456; char c[33] = {0}; IntLength = sprintf( c, "%d", n ); -

I've never seen sprintf with this signature. Have you overloaded it yourself? I think the error you are getting is because you are passing an integer instead of a char*. Instead of: sprintf(IntLength, "%d", Prime); use: IntLength = sprintf( someCharBuffer, "%d", Prime ); Or better yet, use one of the other solutions already given. David
