  Since this question was in the practice section of the first topic, I am assuming you don’t want to use any loop to print the pattern. Hence you can just print the pattern as shown below.

  #include <stdio.h>
  
  int main() {
  	printf("* * * *\n");
  	printf("  * *\n");
  	printf("   *\n");
  	printf("  * *\n");
  	printf("* * * *\n");
  	return 0;
  }
  

  Otherwise, you can print the pattern using the following code.

  #include <stdio.h>
  #include <math.h>
  
  int main(void) {
  	int i, j, k;
  	
  	// printing 1st three rows
  	for(i=0; i<=2; i++) {
  		// printing spaces before first star in each row
  		for(k=i+1; k>0; k--) {
  			if(i>0) {
  				printf(" ");
  			}
  		}
  		// printing stars in each row
  		for(j=pow(2, (2-i)); j>0; j--) {
  			printf("* ");
  		}
  		printf("\n"); 
  	}
  	
  	// printing fourth and fifth rows
  	for(i=1; i>=0; i--) {
  		// printing spaces before first star in each row
  		for(k=i+1; k>0; k--) {
  			if(i>0) {
  				printf(" ");
  			}
  		}
  		// printing stars in each row
  		for(j=pow(2, (2-i)); j>0; j--) {
  			printf("* ");
  		}
  		printf("\n"); 
  	}
  	return 0;
  }
