show all 10 mistakes

Answer 1

The 10 mistakes are given below:

main(void)

{

unsigned int j;

//the following line contains error 1: there are 12 elements so array size will be 12 not 10

//it will be month_days[12]

short int month_days[10]={31,28,31,30,31,30,31,31,30,31,30,31};

//the following line contains error 2: after cout there should be << operator instead <

//the following line also contains error 3: output string should be placed between " " instead of ' '

cout<'DAYS IN EACH MONTH'<<endl;

cout<<"MONTH DAYS"<<endl;

//the following line contains error 4: the syntax of for loop is incorrect ;

// it should be like for(j=0;j<12;j++) : semicolon ';' should be used inplace of comma ','

//the following line also contains error 5: after for loop statement ; should not be placed

//this should be like for(j=0;j<12;j++){...... }

for(j=0,j<12,j++);

{

//the following line contains error 6: array elements should be accessed with help of [] and index

//here only name of the array is given which is wrong ;it should be like month_days[j] instead of month_days

//the following line also contains error 7: this line statement semicolon should be placed

//here at end of line semicolon ';' is missing

cout<<left<<setw(12)<<j+1<<setw(3)<<month_days<<endl

cout<<endl<<endl;

//the following line contains error 8: this line statement should be placed outside of the for loop

//otherwise after every iteration enter should be pressed which is not usual it is kind of logical error

system("pause");

//the following line contains error 9: this line statement should be placed outside of the for loop

//otherwise the loop will end after first iteration only; this is also a logical error

return 0;

}

//Here in the last line there should be a closing '}' which will complete the syntax of main function

//So error 10 : missing of closing bracket '}' for main() function

/********************************************************/

The error free code is given below for understanding purpose:

main(void)

{

unsigned int j;

short int month_days[12]={31,28,31,30,31,30,31,31,30,31,30,31};

cout<<"DAYS IN EACH MONTH"<<endl;

cout<<"MONTH DAYS"<<endl;

for(j=0;j<12;j++)

{

cout<<left<<setw(12)<<j+1<<setw(3)<<month_days[j]<<endl;

cout<<endl<<endl;

}

system("pause");

return 0;

}
