Question

Write a C function named add with the following parameters: three float arrays a, b and c, each of the three arrays is a two dimensional array. The function should add the first two arrays a and b (entry by entry), storing the results in the third array c. In the main function, call the add function with appropriate values. The main function should print the sum of the two arrays stored in the third array. Sample run: float al 2 1[ 31 [[9, 10, 7), 15.6, 20.4, 5.1]; float bl 2 1 31 1.2, 2, 3.43, 3.3, 2, 13 The sum is: 10.200000 12.000000 10.400000 18.900000 22.400000 6.100000

Answer 1

The code is commented and variables are named accordingly.

Code:

#include <stdio.h>

// Declaring size of array globally
int m;
int n;
void add_arrays(float a[m][n],float b[m][n],float c[m][n]){

//Adding arrays
for(int i=0;i<m;i++){

for(int j=0;j<n;j++){

c[i][j]=a[i][j]+b[i][j];

}

}

}
int main(void) {

m=2;
n=3;
float a[2][3]={{9,10,7},{15.6,20.4,5.1}};
float b[2][3]={{1.2,2,3.4},{3.3,2,1}};
float c[2][3];
  
//calling function for adding arrays
add_arrays(a,b,c);
  
printf("The sum is: \n\n");
//printing results
for(int i=0;i<m;i++){

for(int j=0;j<n;j++){

printf("%f ",c[i][j]);

}
printf("\n");

}
   // your code goes here
   return 0;

}

Code Screenshot:

#1nclude <stdio 3 // Declaring size of array globally int m 5 int n 6 void add arrays(float a m] In],float b[m]In,float c[m][n]) //Adding arrays for(int i-0;i<m;i+)( for(int j-0:jn++) 10 12 13 4-int main(void) 15 16 17 18 19 20 21 m-2 n-3 float a[21131 (9,10,7, (15.6,20.4,5.1)); float bl21131-(11.2,2,3.4),[3.3,2,1)) float c[21131 //calling function for adding arrays add arrays (a, b,c); 23 24 25 printf("The sum is: Inn) //printing results for(int i 0;im;i++) for(int j-0;j<n;j++) 27- 28 29 30 31 32 printf("sf "cij); printf("n" your code goes here return θ; 34

Output:

The sum is: 10.200000 12.000000 10.400000 18.900000 22.400000 6.100000
