Re: [algogeeks] c doubt

In C, the type of a character constant like 'a' is actually an int, with size of 4. In C++, the type is char, with size of 1. This is one of many small differences between the two languages. On Thu, Jun 23, 2011 at 6:50 PM, piyush kapoor wrote: > You didn't understand my question... > Why is siz

Re: [algogeeks] c doubt again

there is no as such logic behind it..its just the format specifier... u must be knowing printf returns the number of values it has printed(u can check that) now, in printf if u write like *printf("%7s","a"), *it will create 7 columns for the output and print a in the last column and the returned

Re: [algogeeks] c doubt again

sorry by mistake i added it in scanf situation.. actually this type of specifier can be used with printf statement for finding the sum... look at the code below main() { int a=9; int b=3; printf("%d\n",printf("%*s%*s",a,"",b,"")); system("pause"); } On 6/2

Re: [algogeeks] c doubt again

An asterisk indicates that the data is to be retrieved from the use but ignored, i.e. it is not stored in the corresponding argument...hence the third value entered gets stored for b and for c the output comes to garbage value One beautiful application of such type of implementation is in find

You didn't understand my question... Why is sizeof() interpreting a "constant character literal" as ascii??? -- *Regards,* *Piyush Kapoor,* *CSE-IT-BHU* -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group. To post to this group, send email to al

Re: [algogeeks] c doubt

@piyush Because of its interpretation as ascii .The character's ascii value is taken into account which is an integer . On Thu, Jun 23, 2011 at 6:32 PM, piyush kapoor wrote: > int main() > { > char a; > printf("%d %d",sizeof(a),sizeof('a')); > return 0; > } > Output: > 1 4 > > why do

Re: [algogeeks] c doubt

int main() { char a; printf("%d %d",sizeof(a),sizeof('a')); return 0; } Output: 1 4 why does the expression sizeof('a') evaluates it as an integer,not as a character?? -- *Regards,* *Piyush Kapoor,* *CSE-IT-BHU* -- You received this message because you are subscribed to the Google G
