text: Maximum difference between two elements such that larger element appears after the smaller number |  ; The function assumes that there are at least two elements in array . The function returns a negative value if the array is sorted in decreasing order . Returns 0 if elements are equal ; Driver program to test above function ; Function calling
code: #include <stdio.h> NEW_LINE int maxDiff ( int arr [ ] , int arr_size ) { int max_diff = arr [ 1 ] - arr [ 0 ] ; int i , j ; for ( i = 0 ; i < arr_size ; i ++ ) { for ( j = i + 1 ; j < arr_size ; j ++ ) { if ( arr [ j ] - arr [ i ] > max_diff ) max_diff = arr [ j ] - arr [ i ] ; } } return max_diff ; } int main ( ) { int arr [ ] = { 1 , 2 , 90 , 10 , 110 } ; printf ( " Maximum ▁ difference ▁ is ▁ % d " , maxDiff ( arr , 5 ) ) ; getchar ( ) ; return 0 ; }
