String = "Hello World" String[0:5] print(String)

---

Explaination

Slicing does not change the original string unless reassigned to same variable. Hence, Option A is the answer.

#include<stdio.h> int main() { int n; for (n = 7; n!=0; n--) printf("n = %d", n--); getchar(); return 0; }

---

Explaination

Above loop goes in infinite loop because n is never zero when loop condition (n != 0) is checked.

A driver is driving on the freeway. The check engine light of his vehicle is on, and the driver wants to get service immediately. Luckily, a service lane runs parallel to the highway. It varies in width along its length.

You will be given an array of widths at points along the road (indices), then a list of the indices of entry and exit points. Considering each entry and exit point pair, calculate the maximum size vehicle that can travel that segment of the service lane safely.

Function Description

Complete the serviceLanne function
serviceLane has the following parameter(s)

1.int n: the size of the width array
2.int cases[t][2]: each element contains the starting and ending indices for a segment to consider, inclusive

Try Now

#include<stdlib.h> int main() { int i = 0; for (i=0; i<20; i++) { switch(i) { case 0: i += 5; case 1: i += 2; case 5: i += 5; default: i += 4; break; } printf("%d ",i); } getchar(); return 0; }

---

Explaination

Initially i = 0. Since case 0 is true i becomes 5, and since there is no break statement till last statement of switch block, i becomes 16. Before starting the next iteration i becomes 21.

int ('3' * 3)
