- Question
Write a c program for linear search.
- Correct Answer
- #include
int main(){ int a[10],i,n,m,c=0; printf("Enter the size of an array: "); scanf("%d",&n); printf("Enter the elements of the array: "); for(i=0;i<=n-1;i++){ scanf("%d",&a[i]); } printf("Enter the number to be search: "); scanf("%d",&m); for(i=0;i<=n-1;i++){ if(a[i]==m){ c=1; break; } } if(c==0) printf("The number is not in the list"); else printf("The number is found"); return 0; } Sample output: Enter the size of an array: 5 Enter the elements of the array: 4 6 8 0 3 Enter the number to be search: 0 The number is found

Correct Answer: IHi
Explanation:
It is possible to write label of goto statement in the case of switch case statement.
Correct Answer: rand() returns a random number random() returns a random number in a specified range srand() initialise a random number generator with a given seed value randomize() initializes a random number generator with a random value based o time
Correct Answer: atoi() Converts a string to an integer itoa() Convert an integer to a string gcvt() Converts a floating-point number to a string #include "stdlibh" main() { char s[] = "12345"; char buffer [15], string[20]; int i; i = atoi (s); printf("\n%d",i); gcvt (20141672, 4, buffer); printf ("\n%s", buffer); itoa(15, string,2); printf ("\n%s", string); }
Correct Answer: ptr pointer is constant In ptr = yourbuf the program is trying to modify it, hence an error
Correct Answer: 10
Correct Answer: int a = 1, b , dummy; a > 10 ? b = 20 : dummy =1; Note that the following would not have worked: a > 10 ? b = 20 : ;;
Correct Answer: Till the stack doesn't overflow
Correct Answer: Less Detail flowchart
Explanation:
A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.
Macro flowchart shows the outlines the main segments of program. Macro flowchart is also called as less detail flowchart.
Correct Answer: public abstract class Frob implements Frobnicate { }
Explanation:
B is correct, an abstract class need not implement any or all of an interface?s methods
Correct Answer: Prefix Notation: ^ - * +ABC - DE + FG
