Search an element in a r x c matrix

Search an element in a r x c matrix

Implementation:

Input:

1 2              // first row elements
3 4             // second row elements

5                //element to search

Output:

5 is not found in the array

#include <stdio.h> #include <stdlib.h> #define r 2 //change the row size here #define c 2 //change the column size here int search(int *a[],int element) { int i,j; for(i=0;i<r;i++) { for(j=0;j<c;j++) { if(*(*(a+i)+j) == element) return 1; } } return 0; } int main(void) { /* give the input array while writing the code (static initialization) */ int *a[r]; int i,j,element; /* memory allocation for 2-D array using malloc() function */ for(i=0;i<r;i++) *(a+i)=(int*)malloc(sizeof(int)*c); /* get the input array elements from the user */ for(i=0;i<r;i++) { for(j=0;j<c;j++) { scanf("%d",(*(a+i)+j)); } } printf("enter the element to search in the array :\n"); scanf("%d",&element); /* function call to find the element */ if(search(a,element)) printf("%d is found in the array",element); else printf("%d is not found in the array",element); return 0; }
