Question

1. Write a C code that do the following:

• Generate array of random integer numbers of size 25
• Fill the array with random integers ranging from [1-100]
• Find the maximum number of the array and its location
• Find the minimum number of the array and its location
• Search for a number in the array
• Print the array
• Flip the array
• Sort this array
• Quit the program when the user choose to exit

Answer 1

Program:

#include<stdio.h>
#include<stdlib.h>

void maxAndLocation(int[]);
void minAndLocation(int[]);
void print(int[]);
void search(int[]);
void flip(int[]);
void sort(int[]);

int main()
{
int arr[25];
int i;
char ch;

while(1)
{

for(i=0;i<=24;i++)
{
arr[i]=rand()%(100-1+1)+1;
}

maxAndLocation(arr);
minAndLocation(arr);
print(arr);
search(arr);
flip(arr);
sort(arr);

  
printf("\n\nDo you want to continue(y/n): ");
scanf(" %c",&ch); // a space before %c
if(ch=='n')
{
printf("Bye!!");
break;
}
  
}
return 0;
}

void maxAndLocation(int arr[25])
{
int max=arr[0];
int i,location;
for(i=0;i<=24;i++)
{
if(max<arr[i])
{
max=arr[i];
location=i;
}
}

printf("\nThe maximum number is %d and its location is %d\n",max,location);
}

void minAndLocation(int arr[25])
{
int min=arr[0];
int i,location;
for(i=0;i<=24;i++)
{
if(min>arr[i])
{
min=arr[i];
location=i;
}
}

printf("\nThe minimum number is %d and its location is %d\n",min,location);
}

void print(int arr[25])
{
int i;
printf("\nArray elements: \n");
for(i=0;i<=24;i++)
{   
printf("%d ",arr[i]);
  
}
printf("\n");
}

void search(int arr[25])
{
int i,no,s=0;
printf("\nEnter a number to be searched: ");
scanf("%d",&no);
for(i=0;i<=24;i++)
{
if(arr[i]==no)
{
s=1;
}
}
if(s==1)
{
  
printf("%d is present in the given array\n",no);
}
else
{
printf("%d is not present in the given array\n",no);
}
}

void flip(int arr[25])
{
int i;
printf("\nReverse Array : \n");
for(i=24;i>=0;i--)
{
printf("%d ",arr[i]);
}
  
}

void sort(int arr[25])
{
int i,t,j;
printf("\n\nSorted Array : \n");
  
for(i=0;i<=24;i++)
{
for(j=i+1;j<=24;j++)
{
if(arr[i]>arr[j])
{
t=arr[i];
arr[i]=arr[j];
arr[j]=t;
}
  
}
}
  
for(i=0;i<=24;i++)
{
printf("%d ",arr[i]);
}
  
}

Output:
