C language contest questions how to solve-CodePudding

A very simple question, the question how to write, characters of knowledge completely forget, I remember STRCHR is used to write, but didn't write out good intention person to help me

No man or woman??

CodePudding user response:

This didn't also difficult, write their own good? Too lazy.

CodePudding user response:

Show a, only supplies the reference:

 # include & lt; stdio.h> 
# include & lt; string.h> 

Int yes_or_no (int) c 
{
int result=0; 
If (c=='a' | | c=='e' | | c=='I' | | c=='o' | | c=='u') result=1; 
Else if (c=='A' | | c=='E' | | c=='I' | | c=='O' | | c=='U') result=1; 
return result; 
} 

Int main (void) 
{
Char buf [1001]. 
Char * p; 

While (the fgets (buf, sizeof (buf), stdin)) 
{
If (STRCMP (buf, "end \ n")==0 | | STRCMP (buf, "end of \ r \ n")==0) break; 

P=buf. 
While (* p!='\ 0') 
{
If (yes_or_no (* p)==1) printf (" % c ", * p); 
p++; 
} 
printf("\n"); 
} 

return 0; 
}

Not lazy, I am have not learned the content here...

CodePudding user response:

 
Void out (const char * const STRS, char * out) 
{
Each character traversal STRS 
If the current character is a vowel characters 
Saved to the array out 
Traverse end 

O 
}

Write their own

Yes thank you, excuse me that while the fgets () inside the stdin is what meaning of the sentence, and the sizeof (what inside

Standard input stdin: file pointer, said,
The size of the sizeof: calculate character array buf,
