scanf() returs the number of vlaues read successfully. so
heree the pritf() prints the value that is returned by the
scanf(), ie 2.(a,b). so the output will be 2 and some
garbage value.
what is output of this program
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b;
a=10;
b=20;
printf("%d %d");
getch();
}
it gives the 20 10;
bcoz printf fn return which value,
read recently ,reversely.
so above question we easly explain.
that;-
so scanf fn return which value process it.
scanf fn return 2 and after return value of b.
#include<stdio.h>
void main()
{
int a=5,b=6,c;
int x=(a<b)+7;
int y=(x==7)*9;
int z=(c=x+y)*2;
printf("%h %h %h",x,y,z);
}
What is the output? Explain it.
