1.a=5,b=3,c=a,b
d=(a,b)
printf(c,d)
ans:c=5,d=3
2.e(int n)
{
if(n>0)
{
...(not clear)
printf("%d",n);
e(--n);
}
return
}
ans:0,1,2,0
3.which has no problem with pointers
int *f1()
{
int n;
return (n)
}
int *f2()
{
int *p;
*p=3;
return p;
}
int *f3()
{
int *p;
p=malloc();
return p;
}
ans:no error
4.header file ->contains declarations.
5.sizeof operator is executed during compile time..
6.*p+=1
*p++
are these two same?
not same.
7.func(int i)
{
static int count;
count=count+i;
}
ans:1+2+3...(counts values does not go after funtion call
8.is('a'<'b') true
9.short int=16 bits
10..4 stmt. ans.int float i;
11..int num[3];
num[3]=2;
ans:first stmt deals with size
second deals with element
12.j=4
for(int i=0;i<5;i++)
{
j++;
++j;
}
output of j.
ans:14
13.char s1[20]="hello world";
s1[5]="";
printf("%d",strlen(s1));
printf("%%.%...(not clear)",s1);
}
ans:bad format specifier
14.brace { used in c for what ans:convention
15.parameters in c passed by ans:value.
16.when an array is passed it is by ans:pointer.
17.scanf can read ans:any data type
18.which cant be passed to subroutine.ans:preprocessor
directive.
19.to get string of words..ans:gets()
20.external variables can be accesed ans:in functions which
use them.
