Dans cette rubrique, nous apprendrons comment créer des modèles en utilisant le langage C. Nous allons créer les motifs en utilisant soit un caractère étoile '*', soit un autre caractère. Nous allons créer différents motifs ou une forme géométrique comme un triangle, un carré, etc.

Nous allons aborder les modèles suivants. Vous pouvez visualiser le code de n'importe quel modèle donné ci-dessous en cliquant sur le modèle.

Motif étoile carrée

Le code pour créer le motif étoile carrée est donné ci-dessous :

 #include int main() { int n; printf(&apos;Enter the number of rows&apos;); scanf(&apos;%d&apos;,&amp;n); for(int i=0;i<n;i++) { for(int j="0;j&lt;n;j++)" printf('*'); } printf('
