while(j <= 255)
{
printf(“%c %d “, j, j);
j++;
}
return 0;
}

How many times “javatpoint” is get printed?

Can we use a switch statement to switch on strings?

Which of the following is not logical operator?

We want to test whether a value lies in the range 2 to 4 or 5 to 7. Can we do this using a switch?

In mathematics and computer programming, which is the correct order of mathematical operators ?

Which of the following cannot be checked in a switch-case statement?

Which of the following statements are correct about the below C-program?
#include<stdio.h>
int main()
{
int x = 10, y = 100%90, i;
for(i=1; i<10; i++)
if(x != y);
printf(“x = %d y = %d”, x, y);
return 0;
}
1 : The printf() function is called 10 times.
2 : The program will produce the output x = 10 y = 10
3 : The ; after the if(x!=y) will NOT produce an error.
4 : The program will not produce output.

Which of the following statements are correct about the below program?
#include<stdio.h>
int main()
{
int n = 0, y = 1;
y == 1 ? n=0 : n=1;
if(n)
printf(“Yes “);
else
printf(“No “);
return 0;
}

Which of the following statements are correct about the below program?
#include<stdio.h>
int main()
{
int i = 10, j = 20;
if(i = 5) && if(j = 10)
printf(“Have a nice day”);
return 0;
}

Which of the following statements are correct about the below C-program?
#include<stdio.h>
int main()
{
int x = 10, y = 100%90, i;
for(i=1; i<10; i++)
if(x != y);
printf(“x = %d y = %d “, x, y);
return 0;
}

1 : The printf() function is called 10 times.
2 : The program will produce the output x = 10 y = 10
3 : The ; after the if(x!=y) will NOT produce an error.
4 : The program will not produce output.

Which of the following statements are correct about the below program?
#include<stdio.h>
int main()
{
int i = 10, j = 15;
if(i % 2 = j % 3)
printf(“IndiaBIX “);
return 0;
}

Which of the following sentences are correct about a switch loop in a C program?
1: switch is useful when we wish to check the value of variable against a particular set of values.
2: switch is useful when we wish to check whether a value falls in different ranges.
3: Compiler implements a jump table for cases used in switch.
4: It is not necessary to use a break in every switch statement.

Point out the error, if any in the for loop.

#include<stdio.h>
int main()
{
int i=1;
for(;;)
{
printf(“%d “, i++);
if(i>10)
break;
}
return 0;
}

Which of the following statements are correct about the below program?
#include<stdio.h>
int main()
{
int i = 0;
i++;
if(i <= 5)
{
printf(“Javatpoint “);
exit(0);
main();
}
return 0;
}

Which of the following statements are correct about an if-else statements in a C-program?
1: Every if-else statement can be replaced by an equivalent statements using ?: operators
2: Nested if-else statements are allowed.
3: Multiple statements in an if block are allowed.
4: Multiple statements in an else block are allowed.

Which of the following statements are correct about the program?
#include<stdio.h>
int main()
{
int x = 30, y = 40;
if(x == y)
printf(“x is equal to y “);

else if(x > y)
printf(“x is greater than y “);

else if(x < y)
printf(“x is less than y “)
return 0;
}

Which of the following sentences are correct about a for loop in a C program?
1: for loop works faster than a while loop.
2: All things that can be done using a for loop can also be done using a whileloop.
3: for(;;); implements an infinite loop.
4: for loop can be used if we want statements in a loop get executed at least once.
