Programming language c (pic) exam notes to learn programs

13. Largest of three numbers using nested if-else
#include <stdio.h> int main() { int a,b,c; scanf("%d%d%d",&a,&b,&c); if(a>b){ if(a>c) printf("A is
largest"); else printf("C is largest"); } else { if(b>c) printf("B is largest"); else printf("C is largest"); }
return 0; }
14. Even numbers between 1 to 100
#include <stdio.h> int main(){ int i; for(i=2;i<=100;i+=2) printf("%d ",i); return 0; }
15. Fibonacci series
#include <stdio.h> int main(){ int a=0,b=1,c,n,i; scanf("%d",&n); printf("%d %d ",a,b);
for(i=2;i<n;i++){ c=a+b; printf("%d ",c); a=b; b=c; } return 0; }
17. Star pattern
#include <stdio.h> int main(){ int i,j; for(i=1;i<=5;i++){ for(j=1;j<=i;j++) printf("*"); printf("\n"); } return
0; }
18. Sum of array elements
#include <stdio.h> int main(){ int a[5],i,sum=0; for(i=0;i<5;i++){ scanf("%d",&a[i]); sum+=a[i]; }
printf("Sum=%d",sum); return 0; }
20. Palindrome string
#include <stdio.h> #include <string.h> int main(){ char s[20]; int i,len,flag=0; scanf("%s",s);
len=strlen(s); for(i=0;i<len/2;i++){ if(s[i]!=s[len-i-1]){ flag=1; break; } } if(flag==0) printf("Palindrome");
else printf("Not Palindrome"); return 0; }
