Pyramid Pattern no. 8 using c code /* To print Pyramid Pattern shown below */ #include<stdio.h> int main() { int i,j,n; printf("Enter no. of lines: "); scanf( "%d",&n); //for loop for upper pyramid //for loop for number of lines for(i=1;i<=n;i++) { //for loop for spaces for(j=1;j<=n-i;j++) { printf(" "); } //for loop for stars in first half for(j=1;j<=i;j++) { printf("* "); } //for loop for stars in second half for(j=1;j<i;j++) { printf("* "); } printf("\n"); } //for loop for lower pyramid //for loop for number of lines for(i=1;i<=n-1;i++) { //for loop for spaces for(j=1;j<=i;j++) { printf(" "); } //for loop for stars in first half for(j=1;j<=n-i;j++) { printf("* "); } //for loop for stars in second half for(j=1;j<n-i;j++) { printf("* "); } printf("\n"); } return 0; }

c program to generate, print fibonacci series This program generates Fibonacci series without recursion. You can print as many number of terms of series as desired. C code #include<stdio.h> #include<conio.h>   main ( ) { int n , first = 0 , second = 1 , next , c ;   printf ( "Enter the number of terms " ) ; scanf ( "%d" ,& n ) ;   printf ( "First %d terms of fibonacci series are :- \n " , n ) ;   for ( c = 0 ; c < n ; c ++ ) { if ( c <= 1 ) next = c ; else { next = first + second ; first = second ; second = next ; } printf ( "%d \n " , next ) ; }   getch ( ) ; return 0 ; } Output:

C Program to sort the list of names of persons in alphabetical order using Bubble sort technique #include<stdio.h> #include<string.h> void main(void) { int i,k,n; char*name[50],*temp=""; printf("\nEnter number of persons:"); scanf("%d",&n); for(i=0;i<n;i++) gets(name[i]); for(k=0;k<(n-1);k++) { for(i=0;i<(n-k-1);i++) { if(strcmp(name[i],name[i+1]>0) { strcpy(temp,name[i]); strcpy(name[i],name[i+1]); strcpy(name[i+1],temp); } } } printf("\nSorted List....\n"); for(i=0;i<n;++i) puts(name[i]); }

How to write C Program to calculate L.C.M and G.C.D of two numbers using function #include<stdio.h> void gcd(int,int); void lcm(int,int); int main() {     int a,b;     printf("Enter two numbers: \t");     scanf("%d %d",&a,&b);     lcm(a,b);     gcd(a,b);     return 0; } //function to calculate l.c.m void lcm(int a,int b) {     int m,n;     m=a;     n=b;     while(m!=n)     {         if(m<n)             m=m+a;         else             n=n+b;     }     printf("\nL.C.M of %d  &  %d is %d",a,b,m); } //function to calculate g.c.d void gcd(int a,int b) {     int m,n; ...

Loops in C language For Loop -Most Useful Loops for ( variable initialization; condition; variable inc/dec ) {   Code to execute while the condition is true } While Loop - Simple Loops while ( condition ) { Code to be executed if the condition is true } Do While Loops - It is useful when we want to loop at least once do { } while ( condition );
