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.
Then, we define integer type function "min()" to find the minimum value of an array.
Then, we define integer type "main()" function to call both the functions.
