Question

What are the errors in this program?

/* This program uses a function to read three integer values and uses another function to compute and print their average to two decimal digits i.e. in the form 999.99 */

#include<stdio.h>

void readData (int no1, int no2, int no3 ) ;

int main(void)

{ int n1, n2, n3

// a function call to the function readData to read the numbers.

readData(n1, n2, &n3) ;

//function call to the function to compute and print the average.

computeAverage(n1, n2, n3);

return ;

}

int readData (int* no1, int no2, int no3 )

printf(" Please enter an integer ") ;

scanf_s("%d",n1) ;

printf(" Please enter an integer ") ;

scanf_s("%d",&n2) ;

printf(" Please enter an integer ") ;

scanf_s("%d",&n3) ;

}

void computeAverage(int no1, int no2, int no3) ;

{ float average ;

sum = no1 + no2 + no3 ;

average = sum / 3 ;

printf(" The numbers are: %d , %d ",no1, no2, no3);

printf(" average is: %f", average ) ;

}

Explanation / Answer

/*

error is on lineintreadData (int* no1,intno2,intno3 )

you should pass all three arguments by reference so that any change in value is reflected

so it should beintreadData (int* no1,int*no2,int*no3 )

now correct program is

also there were few ; missing here and there

Here is complete program compiled in dev c++

*/

#include<stdio.h>

int readData (int *no1, int *no2, int *no3 );

void computeAverage(int no1, int no2, int no3) ;

int main(void)

{ int n1, n2, n3;

// a function call to the function readData to read the numbers.

readData(&n1, &n2, &n3) ;

//function call to the function to compute and print the average.

computeAverage(n1, n2, n3);

return ;

}

int readData (int *n1, int *n2, int *n3 ){

printf(" Please enter an integer ") ;

scanf("%d",&n1) ;

printf(" Please enter an integer ") ;

scanf("%d",&n2) ;

printf(" Please enter an integer ") ;

scanf("%d",&n3) ;

}

void computeAverage(int no1, int no2, int no3)

{

float average ;

int sum = no1 + no2 + no3 ;

average = sum / 3 ;

printf(" The numbers are: %d , %d ",no1, no2, no3);

printf(" average is: %f", average ) ;

}
