There are 4 functions in my attached code that print the required shape. They are different. The simplest one is diamond_4 which i think is easy to understand diamond_1,diamond_2 and diamond_3 are a bit difficult to understand. change the cout statements to printf as you require them in c. cout<<"*" to printf("*"); cout<<" " to printf(" "); https://code.sololearn.com/c0XR45S70aka/?ref=app

I meant that the program gets a number from the user then print it

😔😔😔Here it is again..... scanf("%d",&SIZE); for(int x=0;x<SIZE;++x) { for(int sp=0;sp<abs(SIZE/2-x);++sp) printf(" "); for(int y=0;y<2*(SIZE/2-abs(SIZE/2-x))+1;++y) printf("*"); printf("\n"); } EDIT: SORRY forgot that add this to beginning of code int abs(int val) { if(val<0) return val*-1; return val; }

I did that code on visual C but it gives me an error that the abs is not defined, how can I refer the absolute function in the code?

Tested this code this version works #include <stdio.h> int abs(int val) { if(val<0) return val*-1; return val; } int main() { int SIZE; scanf("%d",&SIZE); for(int x=0;x<SIZE;++x) { for(int sp=0;sp<abs(SIZE/2-x);++sp) printf(" "); for(int y=0;y<2*(SIZE/2-abs(SIZE/2-x))+1;++y) printf("*"); printf("\n"); } return 0; }

somewhere in your should be a mistake cause when I run it, it shows infinite stars I mean that somewhere there's an infinite loop!
