Lowercase to Uppercase
#include<stdio.h> int main() { char country[]={'b','a','n','g','l','a','d','e','s','h'}; int i,length; printf("%s\n",country); length=10; for(i=0;i<length;i++){ if(country[i]>=97 && country[i]<=122) { country[i]='A'+(country[i]-'a'); } } printf("%s\n",country); return 0; }
Uppercase to Lowercase
#include<stdio.h> int main() { char country[]={'B','A','N','G','L','A','D','E','S','H'}; int i,length; printf("%s\n",country); length=10; for(i=0;i<length;i++) { if(country[i]>=65 && country[i]<=90) { country[i]='a'+(country[i]-'A'); } } printf("%s\n",country); return 0; }
another method:
#include<stdio.h> int main() { char country[]={'B','A','N','G','L','A','D','E','S','H'}; int i,length; printf("%s\n",country); length=10; for(i=0;i<length;i++) { if(country[i]>=65 && country[i]<=90) { country[i]=country[i]+32; } } printf("%s\n",country); return 0; }
