Answer:
Following are the program in the C Programming Language:
#include <stdio.h> //header file
float avgs(int a[3][4]){ //define function
int s =0, c=0; //set integer type variable
float avg=0; //set float type variable
//set for loops to find sum of an array
for (int i = 0; i < 3; i++){
for (int j = 0; j < 4; j++){
s = s + a[i][j];
c +=1;
}
}
//find average of an array
avg = s / c;
return avg;
}
int min(int a[3][4]){//define function
int m = a[0][0]; //set integer type variable
//set for loop for traversing
for (int i = 0; i < 3; i++)
{ for (int j = 0; j < 4; j++){
if(m > a[i][j])
m = a[i][j];
}
}
return m;
}
int main(){//define main function
int a[3][4];//set integer type Array
printf("Enter the elements of an array:\n");
for (int i = 0; i < 3; i++)
for (int j = 0; j < 4; j++)
scanf("%d", &a[i][j]);
printf("\n Average of an array: %f", avgs(a));
printf("\n Smallest element of an array: %d", min(a));
return 0;
}
Explanation:
Here, we define header file "stdio.h" for print or scan the data.
Then, we define float type function "avgs()" for find the average of an array inside it.
- we set two integer type variable for sum and count
- we set float type variable to store average of an array
- we set the for loops for the sum of an array.
- we divide sum from count to find average and return it.
Then, we define integer type function "min()" to find the minimum value of an array.
- we set integer type variable to store array elements
- we set the for loops for traversing the array
- we set if statement to find minimum value of an array.
- we return the minimum value of an array.
Then, we define integer type "main()" function to call both the functions.
- we set integer type array variable and get input from the user in it with the help of for loops.
- we call both the functions with message and return 0.
