1. The code fragment below finds the maximum and minimum elements in
the integer array arr and stores them in mval[0] (max value) and mval[1]
(min value). Fill in the parts shown by ?m?, m=1 to 8 so that the program
works correctly. n is the size of the array.
Ans:
?1?: int, int
?2?: int, int
?3?: k<n
?4?: max(mval[0], arr[k]);
?5?: min(mval[1], arr[k]);
?6?: k+1
?7?: (a>b)?a:b; or equivalent

1. The code fragment below finds the maximum and minimum elements in

the integer array arr and stores them in mval[0] (max value) and mval[1]

(min value). Fill in the parts shown by ?m?, m=1 to 8 so that the program

works correctly. n is the size of the array.

Ans:

?1?: int, int

?2?: int, int

?3?: k<n

?4?: max(mval[0], arr[k]);

?5?: min(mval[1], arr[k]);

?6?: k+

?7?: (a>b)?a:b; or equivalent

?8?: (a<b)?a:b); or equivalent

8*1=8 marks

2. Consider the following program:

void main()

char a, b;

int c;

scanf(“%c%c%d”, &a, &b, &c);

if (a == ‘a’)

if (b == ‘a’)

printf(“%c\n”, b);

else

printf(“%c\n”, a);

4. Write conditional operators to evaluate the following function

y = 2.4x + 3, for x <= 2

y = 3x – 5, for x > 2

Ans: y = (x<=2)? (2.4x + 3) : (3x - 5) or equivalent

2 marks. No partial marks.

  1. Write a function in C named stringcomp, to perform the task of the strcmp function. Your function will accept two strings to compare, and return an integer measuring the difference. Ans: int stringcomp(char str1[], char str2[]) { int ret = 0; for (int i = 0; 1; i++) { if (str1[i] != str2[i]) { return str1[i]-str2[i]; } if (str1[i] == '\0' || str2[i] == '\0') return 0; } } Students may write the same code in different ways. 5 marks
  2. See the following code segment: char arr[3][4]={‘a’,’z’,’b’,’y’,’c’,’x’,’d’,’w’,’e’,’v’,’f’,’u’}; printf(“%d\n”, arr[1][2]); What will be printed? Ans: 100 2 marks, no partial marks.
  3. What will be the output of the following code segment: char s[10]=”Hello”; int i;

for(i=0;s[i]!=’\0’;i++); printf(“%d\n”, i); Ans: 5 2 marks Only one value will be printed. Marks will be given only for this answer. For any other answer (even containing 5) will get 0 marks.

  1. Write an appropriate macro such that, it will accept the marks and return “pass” if the marks is more than 60; and “fail” otherwise. Ans: #define grade(marks)(marks>60)?"pass":"fail" 2 marks No partial marks

See the code below: #include<stdio.h> int hello(int n) { return n++; } void main() { int n=5; n=hello(n++); printf("%d"\n, n); } What will be printed? Use the two '++' operators in suitable ways so that the output is 7. Answer: 5 Write ++n in place of n++ for both the cases. 2 marks: 1 mark for each correct answer
