This program will add an integer number and a decimal number up to 2 decimal places. I have included notes in the code to explain what each thing does. I hope I did this right. It compiles successfully.
PseudoCode
Start
Declare int O1; Stands for Output1
O1=sum; Sum is the functions name
Int sum()
Declare variables
Int num1;
Float num2;
Write “Enter a number.”
Scanf num1
Write”Enter a decimal number.”
Scanf num2
Return num1+num2
end
C Code
#include <stdio.h>
int sum();//prototype
int main()//calling program
{
//Declare a varaiable
int O1;
O1=sum();//main is calling sum one time.
//if I listed this twice it would run the function 'sum' twice.
// Example: if I add a new int (int O1, O2) and declare O2 to
//be O2=sum then the function would run twice.
}
int sum ()//function 'sum'
{
int num1;// Declare intergers/variables
float num2;
printf("Enter a number.\n");
scanf("%d",&num1);// Take first input and assign it to num1
printf("Enter a decimal number.\n");
scanf("%.2f",&num2);
//Can use the printf statement but when you are calling an integer you can use the return.
//printf("The sum of %d, %d, is %d", num1,num2,num1+num2);
return num1+num2;
}

1. Two arrays are provided, one float array and one integer array. Functions are used to display the highest number from the float array and the lowest number from the integer array. The first function (gettable) will determine the lowest number from the designated set in the “main” function. Then the second function (getTable) will determine the highest number from the designated set in the “main” function. So the expected output for this pseudocode should be:
“High number= 4
Low number= 7.8”
The only possible error I see here is that there might be an error with data types. It looks like when the “table1” array is defined it is of the float data type, but the function pseudocode for “getTable” is requesting integer data type. I thought that this might cause an error when the function “getTable” is called because of different data types.
Has anyone noticed the same or am I incorrect? Professor? Class?
2. Algorithm and C code posted below! Took me a few tries to figure out the best approach here.
//Pseudocode
//This program will accept input of positive integers terminated by 0, then determine
//the largest integer that was entered
//Largest integer function
Declare function largest_number as integer
Declare largest,j as integer
Set j=0
Set largest=user_array element 0
While(j<100000)
If(largest<user_array[j]) then
Set largest=user_array[j]
End if
Increment j
End while
Return largest
End function
Main function
//Declare variables
Declare user_array[100000] as integer
Declare number, i, q, largest as integer
//Initialize the array
for(q=0;q<100000;q++)
user_array[q]=0
//Initialize variables
set i=0
//While loop for array entry
while(i<100000)
print “please enter a positive integer: “
input number
if(number==0) then
break
end if
set user_array[i]=number
increment i
//Print largest number
largest=largest_number(user_array)
print “The largest number is: “
return 0
End program
C code:
//
// main.c

#include <stdio.h>

//largest integer function
int largest_number(int user_array[])

j=0;
largest=user_array[0];
while(j<100000)
{
if(largest<user_array[j])
{
largest=user_array[j];
}
j++;
}
return largest;
}
int main()

//Declare variables

int number,i,q,largest;
//Initialize array
for(q=0;q<100000;q++)
{
user_array[q]=0;
}
//Initialize variables
i=0;
//while loop for array entry
while(i<100000)
{
printf("Please enter a positive number: \n");
scanf("%d",&number);
if(number==0)
break;
user_array[i]=number;
i++;
}
//Print largest number
largest=largest_number(user_array);
printf("The largest number is: %d\n",largest);
return 0;

Hello all;
1) The output I got is:
High number = 4
Low number =7.8
2) I created function to return maximum number from 3 values.
#include <stdio.h>
//Set getMax function from array
int getMax(int number[]) {
//Declare integer i, max int i, max;
//Set value for max max = number [0];
//Set i to zero i=0;
//Set condition while loop while (i< 3) { scanf("%d", &number[i]); if(max<number[i]) { max=number[i]; } i=i+1; } return max; } main () {
/*Declare number[3], max, and i as integer*/ int number[3], max, i;
/*Set value for max*/ max = getMax(number[0]);
/*Print result*/ printf("Max is =%d\n",max); }
