Control Instructions

The keyword ‘break’ cannot be simply used within:

#include 
 
int main()
{
    unsigned int i = 65000;
    while (i++ != 0);
    printf("%d", i);
    return 0;
}

The output of the code below is

#include 
    void main()
    {
        char *ch;
        printf("enter a value btw 1 to 3:");
        scanf("%s", ch);
        switch (ch)
        {
        case "1":
            printf("1");
            break;
        case "2":
            printf("2");
            break;
        }
    }

Which loop is guaranteed to execute at least one time.

Which of the following is correct with respect to “Jump Statements” in C?

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.

Consider the following pseudocode:

x:=1;
i:=1;
while (x ≤ 500)
begin
x:=2x ;
i:=i+1;
end

What is the value of i at the end of the pseudocode?

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

What will be the output of the program?

#include
int main()
{
    int i = 5;
    while(i-- >= 0)
        printf("%d,", i);
    i = 5;
    printf("\n");
    while(i-- >= 0)
        printf("%i,", i);
    while(i-- >= 0)
        printf("%d,", i);
    return 0;
}
