C Language Multiple Choice Questions from Aditi Technical Questions Part:

  NOTE: All questions are multiple choice / objective type from c programming language.

1. What is the output of the program given below

   #include<stdio.h>
        main()
       {
          char i=0;
          for(;i>=0;i++) ;
          printf(“%d\n”,i);
       }

2. What is the output of the following program

   #include<stdio.h>
      main()
        {
          int i=0;
          fork();
          printf(“%d”,i++);
          fork();
         printf(“%d”,i++);
         fork();
         wait();
        }

3. What is the memory allocated by the following definition ?
     int (*x)[10];

4.  What is the memory allocated by the following definition ?
   int (*x)();

5. In the following program segment
   #include<stdio.h>
        main()
       {
         int a=2;
         int b=9;
         int c=1;
        while(b)
     {
        if(odd(b))
        c=c*a;
       a=a*a;
       b=b/2;
     }
   printf(“%d\n”,c);
   }

   How many times is c=c*a calculated?

6. In the program segment in question 5 what is the value of a at the end of the while loop?

7. What is the output for the program given below

        typedef enum grade{GOOD,BAD,WORST,}BAD;
        main()
       {
           BAD g1;
           g1=1;
           printf(“%d”,g1);
        }

8. Give the output for the following program.
   #define STYLE1 char
         main()
        {
         typedef char STYLE2;
        STYLE1 x;
        STYLE2 y;
        clrscr();
        x=255;
        y=255;
        printf(“%d %d\n”,x,y);
        }

9. In the following program
    #include<stdio.h>
     main()
      {
       char *pDestn,*pSource=”I Love You Daddy”;
       pDestn=malloc(strlen(pSource));
       strcpy(pDestn,pSource);
       printf(“%s”,pDestn);
       free(pDestn);
    }
     (a)Free() fails
     (b)Strcpy() fails
     (c)prints I love You Daddy
     (d)error

10. What is the output for the following program
         #include<stdio.h>
           main()
          {
          char a[5][5],flag;
          a[0][0]=’A';
          flag=((a==*a)&&(*a==a[0]));
          printf(“%d\n”,flag);
          }

As you can see, most of the above questions from the Aditi placement exam paper were from the C / C++ programming language where you were given the c code and you have to find out the error messages in output or the output of the program when its executed. These latest questions were for the recruitment test of electronics, computer science or IT graduate or diploma students. We have more 2008 latest questions here.
