9. caseConversion

 

PROGRAM:

# include <lpc21xx.h>

char src[ ] = "rns institute of technology";

char dest[ ] = ""; OR dest[50];

void caseConvert(){

unsigned int i;

for (i = 0; src[i]!='\0'; i++){

if(src[i] >= 'a' && src[i] <= 'z') {

dest[i] = src[i] - 32;

}

if(src[i] >= 'A' && src[i] <= 'Z') {

dest[i] = src[i] + 32;

}

}

}

int main(){

caseConvert();

return 0;

}
