Use for loops to print the stars, the spaces, etc. The standard for loop structure is one of the following two

for( int i = 0; i < numberOfTimes; i++ )
for( int i = 1; i <= numberOfTimes; i++ )

for loop number of lines
{

for loop spaces
{

print space
}

for loop stars

{

print star, print space

}
print newline

}

}

Edit:
BTW, the number of spaces to print is equal to the TotalNumberOfLines - CurrentLineNumber
The number of stars to print is equal to the CurrentLineNumber
