Question

 53.  Rewrite the if statement below using only the relational operator < in all conditions. Assume that the value of score is between 0 and 100 inclusive.

 54.  Rewrite the following code segment as an equivalent segment that uses a do-while statement.

 55.  Assuming the following declaration:

 char my array[9] - ['C', 'p', 't', 'S', '9, '1', '2', '1']; 

What is the value of*(my array +4)?

Answer 1

//53.using < symbol only
#include
main()
{
   int score;
   printf("Enter score(0-100):");
   scanf("%d",&score);
   if(score<80)
       printf("C\n");
   else if(score<90)
       printf("B\n");
   else
       printf("A\n");
}

1 1/53. using < symbol only 2 #include 3 main() 49 C 5 int score; 6 printf("Enter score(0-100):"); 7 scanf("%d", &score); 8 if(score<80) 9 printf("C\n"); 10 else if(score<90) 11 printf("B\n"); 12 else 13 printf("A\n"); 14 )

Enter score (0-100):56 с

//54.using do while
#include
main()
{
   int sum=0,next=1,bound=10;
   do {
sum+=(++next);
}while(next printf("sum=%d",sum);

}

sum=54

//55.*(my_array+4) prints value of 4th index
#include
main()
{
   char my_array[9]={'c','p','t','s',' ','1','2','1'};
   printf("%c",*(my_array+4)); //here 4th index is space.so it prints space
}

1 //55. *(my_array+4) prints value of 4th index 2 #include 3 main() 490 5 char my_array[9]={'c','p', 't', 's',' ','1','2', '1'}; 6 printf("%c",*(my_array+4)); //here 4th index is space. so it prints space 7 }

Process exited after 1.287 seconds with return value 32 Press any key to continue .
