Find the maximum length of the subarray in increasing order.

For example we have an array {5,4,6,-2,-1,0,1,9}. The biggest sub-array in increasing order is: {-2,-1,0,1,9}. So the length is 5.

#include<stdio.h>
void main () {
int arr[8] = {5,4,6,-2,-1,0,1,9},i,arrn[8],count=1,j=0,max;
printf("The given array is: ");
for(i=0;i<8;i++)
    printf("  %d" ,arr[i]); // printing the actual array  - unnecessary step.
printf("\n");
for(i=0;i<7;i++){
        if(arr[i]<arr[i+1])
        {
            count++;
        }
        else
        {
            arrn[j]=count; // adding the length of sub array
            count=1;
            j++;
        }
}
arrn[j]=count; // adding the final length
max=arrn[0];
printf("Length of sub arrays in increasing order");
for(i=0;i<=j;i++){
        if(max<arrn[i])
            max=arrn[i];
        printf(" %d",arrn[i]);  // printing the new array  - unnecessary step.
}
        printf("\n Maximum Length of the substring: %d",max); // print max value
}

   

Output
The given array is:   5  4  6  -2  -1  0  1  9
Length of sub arrays in increasing order 1 2 5
Maximum Length of the substring: 5

Find the maximum occurrence of a character in a string

#include<stdio.h>
#include<conio.h>

int main() {
   char str[20], ch;
   int count = 0, i,j=0 , max;
   int arr[10];
   printf("\nEnter a string : ");
   scanf("%s", &str);

   printf("\nEnter the character to be searched : ");
   scanf("%c", &ch);
   for (i = 0; str[i] != '\0'; i++) {
      if (str[i] == ch)
         count++;
      else if(count != 0)
      {
          arr[j] = count;
          j++;
          count = 0;
      }
   }
   arr[j]=count;
   max = 0;
       for(i=0;i<=j;i++)
        if(max<arr[i])
         max=arr[i];
   if (max == 0)
      printf("\nCharacter '%c'is not present", ch);
   else
   {
       printf("\nMaximum occurrence of character '%c' : %d", ch, max);
   }
   return (0);
}

   

Output

Enter a string : aabbbaaab

Enter the character to be searched :
Maximum occurrence of character 'a' : 3

Accept Array elements

#include<stdio.h>
void main() {
   int arr[10], i, j, k, size;
   printf("\nEnter array size : ");
 scanf("%d", &size);

   printf("\nAccept Numbers : \n");
   for (i = 0; i < size; i++)
 {
 printf("Data [%d]: ",i+1);
 scanf("%d", &arr[i]);
 }

   printf("\nThe Array is : ");
   for (i = 0; i < size; i++)
 printf("%d ", arr[i]);

    getch();
}

   

Output

Enter array size : 5

Accept Numbers :
Data [1]: 2
Data [2]: 6
Data [3]: 7
Data [4]: 1
Data [5]: 2

The Array is : 2 6 7 1 2
