Basics of C Language

 What will be the output of the following C code? 

If following commands are used to run(considering myfile exists)?
gcc -otest test.c
./test < myfile

#include <stdio.h>
    int main()
    {
        char c = 'd';
        putchar(c);
    }

What is the output of this program?

           
#include <stdio.h>
int demo()
{
  static int i = 0;  
  printf("%d ",i++);
}
int main()
{
  for(int j = 0 ; j < 5 ; j++ )
  {
      demo();
  }
}

 Predict the output of following program.

#include <stdio.h>

int main()
{
    int a=10;
    int b=2;
    int c;
    
    c=(a & b);
    printf("c= %d",c);
    
    return 0;
}

In C programming language, which of the following type of operators have the highest precedence?

Which among the following is NOT a logical or relational operator?

What is the result of logical or relational expression in C?

void main()

{

      int i=0,j-1,k=1,m;

      m= i++ || j++  || k++

      printf("%d %d %d %d", m, i, j, k)

}

 Which of the following is not a valid variable name declaration?

What will be the output of the following code snippet?

#include <stdio.h>
int main() {
    int a = 3, b = 5;
    int t = a;
    a = b;
    b = t;
    printf("%d %d", a, b);
   
}

Which is the part of the structure of a C program?

Which is Procedural Oriented language?

Study the following statement
for $\left(i=3 ; i<15 ; i+=3\right)$
{Print $f\left("\%d^{\text{'}\text{'}},i+\right)$; $++i;$}
What will be the output?

The following programme fragment
int $\mathrm{a}=4, \mathrm{b}=6$
print $f\left("\%d", a=b\right)$

The following programme fragment
int $\mathrm{a}=4, \mathrm{b}=6$
print $f\left("\%d",a!=b\right)$

The following programme fragment
for $\left(i=3 ; i<15 ; i+=3\right)$;
print $f\left("\%d",i\right)$;
result in :

Study the following statement

Print $f\left("\%f",\frac{9}{5}\right)$

What will it print?

Study the following programme fragment

$\mathrm{int} i=263$

putchar $\left(\mathrm{i}\right)$

What it does?

print $f\left("\%c",100\right)$

From the following comments about the $++$ operator, which are correct?

$x-=y+1;$ means
