-
Find the output of the following program.
#include<stdio.h>
void main()
{
int y=10;
if(y++>9 && y++!=10 && y++>11)
printf("%d", y);
else
printf("%d", y);
}
-
What will be the value of sum after the following program is executed?
void main()
{
int sum=1, index = 9;
do{
index = index – 1;
sum *= 2;
}while( index > 9 );
}
-
What is the right choice, if the following loop is implemented?
void main()
{
int num = 0;
do{
--num;
printf("%d", num);
}while( ++num >= 0 );
}
-
What will be the final value of the digit?
void main()
{
int digit = 0;
for( ; digit <= 9; )
digit++;
digit *= 2;
--digit;
}
-
What will be the following code's output if choice = 'R'?
switch(choice)
{
case 'R' : printf("RED");
case 'W' : printf("WHITE");
case 'B' : printf("BLUE");
default : printf("ERROR");break;
}
-
Consider the following program fragment:
for(c=1, sum=0; c <= 10; c++)
{
scanf("%d", &x);
if( x < 0 ) continue;
sum += x;
}
What would be the value of sum for the input 1, -1, 2, -2, 3, -3, 4, -4, 5, -5
-
What will be printed if the following code is executed?
void main()
{
int x=0;
for( ; ; )
{
if( x++ == 4 ) break;
continue;
}
printf("x=%d", x);
}
-
Consider the following code:
void main()
{
int a[5] = {6,8,3,9,0}, i=0;
if(i != 0)
{
break;
printf("%d", a[i]);
}
else
printf("%d", a[i++]);
}
