Programming for Problem Solving using C language

In which year was C language developed?

True statement(s) for C language is

A) Procedural oriented programming language

B) General purpose programming language

C) Structured programming

Consider the following code:

struct node
{
    int i;
    float j;
};
struct node *s[10];

Which one is the valid statement for the above code?

Consider the following code:

#include <stdio.h>
int main()
{
    int i = 3;
    printf("%d", (++i)++);
    return 0;

What is the output of the above code?

Which is/are the correct syntax to initialize an array in C?

A. data_type array_name[array_size] = {value1, value2, value3, ...};

B. data_type array_name[] = {value1, value2, value3, ...};

C. data_type array_name[array_size] = {};

Consider the following code:

#include <stdio.h>
union test { int x; char arr[8]; int y; };
int main()
{
    printf("%lu", sizeof(union test));
    return 0;
}

What is the size of the union based on above program where each integer size has 4 bytes and character has 1 byte.

Consider the following code:

#include <stdio.h>
#define PRINT(i, limit) do \\
    { \\
        if (i++ < limit) \\
        { \\
            printf(\"MGCU\\n\"); \\
            continue; \\
        } \\
    } while(0);

int main() {
    int i = 0;
    PRINT(i, 3);
    return 0;
}

How many times MGCU is printed in the above program ?

Consider the following code:

#include <stdio.h>
int main() {
    int i;
    if (printf("0") > 0)
        i = 3;
    else
        i = 5;

    printf("%d", i);
    return 0;
}

What is the output of the above code?

Consider the following code:

#include <stdio.h>
int main() {
    int c = 5, no = 10;
    do {
        no /= c;
    } while(c--);

    printf(\"%d\\n\", no);
    return 0;
}

What is the output of above code?

Consider the following code:

#include<stdio.h>
int main() {
    int a = 5;
    switch(a)
    {
        default:
            a = 4;
        case 6:
            a--;
        case 5:
            a = a + 1;
        case 1:
            a = a - 1;
    }
    printf(\"%d\\n\", a);
    return 0;
}

What is the output of the above code?
