Repeat the Program for again Search Array Element - c

Question

Repeat the Program for again Search Array Element.
#include <stdio.h>
#define MAX_SIZE 100
int main()
{
int arr[MAX_SIZE];
int size, i, toSearch, found;
char repeat;
printf("Enter the size of an array\n");
scanf("%d", &size);
printf("Enter the array elements\n");
for (i = 0; i < size; i++)
{
scanf("%d", &arr[i]);
}
do{
printf("\nEnter element to search: ");
scanf("%d", &toSearch);
found = 0;
for(i=0; i<size; i++)
{
if(arr[i] == toSearch)
{
found = 1;
break;
}
}
if(found == 1)
{
printf("\n%d is found at position %d", toSearch, i + 1);
}
else
{
printf("\n%d is not found in the array \n", toSearch);
}
printf("\n \n \nPress Y to again Search Any Element in Array\n \nPress Any other Key to Exit the Program\n\n");
scanf(" %c \t",&repeat);
}
while(repeat == 'y' || repeat == 'Y' );
return 0;
}
I want to repeat my program when user give the input of Y || y otherwise it'll exit the program.
In this code i want to make an array then search the element after this show's the results and in last repeat the code from the search the element block.

Answer 1

I ran your code and everything seems to be working properly except for this line:
scanf(" %c \t",&repeat);
Remove the \t from the scanf and it should work properly. You don't want to scan for a tab character, just the 'Y' or 'y' character.
Also, your use of newlines is a bit unusual. Try putting newline characters at the end of your strings as opposed to the beginning.
Updated code:
#include <stdio.h>
#define MAX_SIZE 100
int main() {
int arr[MAX_SIZE];
int size, i, toSearch, found;
char repeat = ' ';
printf("Enter the size of an array\n");
scanf("%d", &size);
printf("Enter the array elements\n");
for (i = 0; i < size; i++)
scanf("%d", &arr[i]);
do{
printf("Enter element to search: \n");
scanf("%d", &toSearch);
found = 0;
for(i=0; i<size; i++) {
if(arr[i] == toSearch) {
found = 1;
break;
}
}
if(found == 1)
printf("%d is found at position %d\n", toSearch, i + 1);
else printf("%d is not found in the array\n", toSearch);
printf("Press Y to again Search Any Element in Array\nPress Any other Key to Exit the Program\n");
scanf(" %c",&repeat);
}
while(repeat == 'y' || repeat == 'Y' );
return 0;
}

Enclose the block of code you want to repeat in a while loop, something like
bool flag = false;
while(flag==true) {
//Code block
scanf("%c",&input)
if((input == 'y') || (input == 'Y')) {flag = true;}
else {flag = false;}
}

The first method that came to my mind :
#include <stdio.h>
#define MAX_SIZE 100
int main()
{
int arr[MAX_SIZE];
int size, i, toSearch, found;
char repeat;
printf("Enter the size of an array\n");
scanf("%d", &size);
printf("Enter the array elements\n");
for (i = 0; i < size; i++)
{
scanf("%d", &arr[i]);
}
do
{
printf("\nEnter element to search: ");
scanf("%d", &toSearch);
found = 0;
for (i = 0; i < size; i++)
{
if (arr[i] == toSearch)
{
found = 1;
break;
}
}
if (found == 1)
{
printf("\n%d is found at position %d", toSearch, i + 1);
}
else
{
printf("\n%d is not found in the array \n", toSearch);
}
printf("\n \n \nPress Y to again Search Any Element in Array\n \nPress Any other Key to Exit the Program\n\n");
repeat = getchar();
repeat = getchar();
if(repeat == 'y' || repeat == 'Y') {
continue;
}
else {
break;
}
} while (1);
return 0;
}
