Question

Write a C program in Unix which uses a function called search to find

the location of a value in THREE arrays of floats. The function should

take three parameters :

         the value to be found

         the array to be searched

         the size of the array

N.B.!!!! The main program should read in three arrays of varying size

         example : array a has twelve elements

                   array b has six elements

                   array c has nine elements

                   array d has four elements

         input to these arrays terminated by illegal input(see handout)

         the function should return for each array the index where the

         value is found. If not found the function should return -1.

Answer 1

#include <stdio.h>

int search(float value, float arr[], int size) {
        
        for(int i=0; i<size; i++) {
                if(arr[i] == value) {
                        return i;
                }
        }
        
        return -1;
}

int main(void) {
        float a[12] = {3.4, 4.5, 6.5, 2.2, 2.1, 3.2, 4.5, 4.5, 7.2, 7.1, 8.9, 9.5};
        float b[6] = {3.4, 4.5, 6.5, 2.2, 2.1, 3.2};
        float c[9] = {3.4, 4.5, 6.5, 2.2, 2.1, 3.2, 4.5, 4.5, 7.2};
        float d[4] = {3.4, 4.5, 6.5, 2.2};


        printf("Index of 2.1 in a: %d \n", search(2.1, a, 12));
        return 0;
}
