int x = 65; for (int i = 1; i < 5; i++) { for (int j = 0; j < i; j++) { cout << static_cast<char>(x); x++; } cout << endl; }

I tried this way.. #include <iostream> using namespace std; int main() { char ch='A'; for(int i=1;i<=4;i++) {for(int j=0;j<i;j++) { ch++; cout<<" "<<ch; } cout<<" "<<endl; } return 0; } But the out put is: B C D E F G H I J K Can u explain why?

yeah. in your j for loop, try placing the ch++ below the cout. it is incrementing before the first print. hence you get B

//ASCII value of A is 65. so, solving by typecasting , x = 65; for(j=0;j<4;j++) { for(i=0;i<j+1;i++) printf("%c ",(char)x++); printf("\n"); } //you could also define a character array with those values and run it on a loop
