Q1) What is the output displayed by the below program?

#include <stdio.h>
int main(void)
{
   char a[5]={'1','x','2'};
   printf("%d",a[2]);

   return 0;
}

Q2) Assume int is given 2 bytes space for the array a[5][5].
Identify the memory location at which a[2][3] will be if row-major order is considered?

The base address of the array a is given 2000 location by the compiler.

Q3) What is the output displayed by the below program?

#include <stdio.h>
int main(void)
{
   int a[3][3]={1,2,3,4,5,6,7,8,9},i,j;
   for(i=0;i<3;i++)
           for(j=0;j<3;j++)
           {
                   if(i>=j)
                   {
                           a[i][j]+=1;
                   }
           }
        printf("%d",a[i][j]);

   return 0;
}

Q4) What is the output displayed by the below program?

#include <stdio.h>
int main(void)
{
   char p[20]={'r','e','s','p','e','c','t',' ','e','l','d','e','r','s','\0'};
   char b[20];
   int k=0;
   while(p[k]!='\0' && p[k]!=' ')
   {
           b[k]=p[k];
           k++;
   }
   k=0;
   while(b[k]!='\0')
   {
           printf("%c",b[k]);
           k++;
   }

   return 0; 
}

Q5) How many numbers of 1’s in the array a, after executing the below program?

#include <stdio.h>
int main(void)
{
   int a[4][5]={1,3,5,7,9},i=0,j=0;
   for(i=0;i<4;i++)
           for(j=0;j<5;j++)
                   a[i][j]+=1;

   return 0; 
}
