Star Triangle Left Triangle #include <stdio.h> int main() { int n ; printf("Enter Number of rows:"); scanf("%d", &n); for(int i=1; i<=n;i++){ for(int j=1; j<=i; j++){ printf("%c",64+j); } printf("\n"); } return 0; } In C, braces { } group multiple statements into a block. You can skip them for a single statement, but using { } is safer and improves readability. ...
