hey guys, I have a question, Say I have a function which takes file as an argument, (file can be **argv contents or stdin), my main problem is that I don't know how to pass stdin as argument to that function

How do I get this solve.

This which one should i use?

How can I compile an app for x86-16 (such as 8086, 80286) with a modern C++ compiler (I think a modern C++ compiler should support at least C++11.). (I know I can use OpenWatcom to compile 16-bit apps, but that compiler don't support C++11.)

void foo( FILE * stream ) ....

#include<stdio.h> int main() { int n,i=3,c,count; printf("\n Enter the number:"); scanf("%d,&n"); if(n>=1) { printf("\n Prime Numbers"); printf("2"); } for(count=2;count<=n;count++) { for(c=2;c<=i;c++) { if(i%c==0) break; } if(c==i) { printf("%d",i); count++; } } return 0; } Can anyone make me understand this code ?

Understand? I can’t even read it.

#include<stdio.h> int main() { int n,i=3,c,count; printf("\n Enter the number:"); scanf("%d,&n"); if(n>=1) { printf("\n Prime Numbers"); printf("2"); } for(count=2;count<=n;count++) { for(c=2;c<=i;c++) { if(i%c==0) break; } if(c==i) { printf("%d",i); count++; } } return 0; } Can anyone make me understand this code ?

Lol he/she deserves a warn

#include<stdio.h> int main() { int n,i=3,c,count; printf("\n Enter the number:"); scanf("%d,&n"); if(n>=1) { printf("\n Prime Numbers"); printf("2"); } for(count=2;count<=n;count++) { for(c=2;c<=i;c++) { if(i%c==0) break; } if(c==i) { printf("%d",i); count++; } } return 0; } Can anyone make me understand this code ?

Can anyone make me understand this ?

What don't you understand?

The code itself

Ya I know I just arranged in hurry

Isn't that C thing?

It is.

then any other way?

files := os.Args[1:] var source string if len(files) == 0 { someFunc(os.Stdin) source = "Stdin" } else { for _, arg := range files { source = arg v, err := os.Open(arg) if err != nil { fmt.Fprintf(os.Stderr, "someProgram: %v\n", err) continue } someFunc(v) v.Close() } }

Your needed this, did you?

but in C++

yep

but in C++

You can use std::ifstream for opening a file, and std::cin for reading from stdin

Why? if there is a such good lang as Go?

istream* I dont think we can open std::cin as std::ifstream

but in C++

You can do something like void foo( std::istream& in );

no matching function for call to 'out'

stdin is of type FILE* if you want to use istream& you should pass std::cin https://en.cppreference.com/w/cpp/io/cin

Share your code with paste.ubuntu.com

what's wrong in that?

Publish your code on pastebin.com or similar

the result came out but printout the wrong output since the formula is wrong

These expressions in printf are valid, but semantically useles printf("\t%.2f\t\t\t%.2f\t\t\t%.2f\n", AIR, P= P= (r*LoanAmount)/(1- pow(1+r,-N)), TP=P*N); try rewriting the statement.

I see, sorry for the double P= typo inside the coding, even without it the result is the same, but the the P= is supposed to be write like below pic

even without p = p = .... (that is , p = ... ) this would be very strange.

I see, sorry I'm not good when it come to math statement writing, nevermind I'll try to fix that up, tq for point of the mistake though 😁 appreciate it

The formula for P is actually OK. You also must know what UB is, you have it in the code. You cannot calculate a variable and use it in the same full expression for other subexpression. Put variables assignments outside PRINTF call.

I see, so I have to separate the variable first and make sure it work then only I can make it as full expression

get a job lol
