text: Linear Search | C code to linearly search x in arr [ ] . If x is present then return its location , otherwise return - 1 ; Driver code ; Function call
code: #include <stdio.h> NEW_LINE int search ( int arr [ ] , int n , int x ) { int i ; for ( i = 0 ; i < n ; i ++ ) if ( arr [ i ] == x ) return i ; return -1 ; } int main ( void ) { int arr [ ] = { 2 , 3 , 4 , 10 , 40 } ; int x = 10 ; int n = sizeof ( arr ) / sizeof ( arr [ 0 ] ) ; int result = search ( arr , n , x ) ; ( result == -1 ) ? printf ( " Element ▁ is ▁ not ▁ present ▁ in ▁ array " ) : printf ( " Element ▁ is ▁ present ▁ at ▁ index ▁ % d " , result ) ; return 0 ; }
